Key takeaways
- Sender leads for most senders: 2,500 subscribers and 15,000 emails a month free, then $9 a month; Brevo follows with 300 free emails a day, and Kit stays free to 10,000 subscribers.
- The single most important buying factor is the free plan's send cap: daily caps of 200 to 300 emails decide whether a blast goes out in one day or over weeks.
- Every tool here has a genuinely free plan, but only Sender and Brevo pair a generous free tier with a $9-a-month first paid plan.
- Annual billing cuts the first paid plan to about $97 to $187 a year on most tools here — except Mailchimp, which publishes no annual discount below 10,000 contacts.

Sender
Best for: Small businesses that want the biggest free plan in this list and real automation before paying anything
Sender is the free-plan leader in this list by a wide margin: the Free Forever plan covers 2,500 subscribers and 15,000 emails a month, with automation workflows and segmentation included. Standard starts at $9 a month for 500 subscribers and 6,000 emails, adds three seats, removes Sender branding and opens SMS, while Professional at $15 adds deeper automation and priority support.
The catch is the template library, which is smaller and less modern than Mailchimp or MailerLite, and the integration list is shorter than the big-name platforms. The $6.30-a-month annual figure is a first-year discount that renews at $9, so budget on $9. Choose Sender when your list is under 2,500 and you want the longest free runway in this list; choose Brevo when your list is bigger and you email it rarely.
What we like
- The biggest free plan here: 2,500 subscribers and 15,000 emails a month at $0
- Automation workflows and segmentation run on the free plan, not just paid tiers
- Standard at $9/month includes 3 user seats and removes Sender branding
- Reviewers praise the live chat support for fast, human answers
Watch out for
- Template selection is smaller and less modern than Mailchimp or MailerLite
- The $6.30 annual figure is a first-year discount; it renews at $9/month
- Fewer third-party integrations than the big-name platforms here
Brevo
Best for: Senders with a large list who email a few times a month and want to pay by volume sent, not contacts stored
Brevo flips the usual pricing logic: you pay for emails sent, not contacts stored. A 50,000-person list mailed once a month costs the same as a 5,000-person list mailed weekly, which makes it the value pick for businesses with large, quiet databases. The free plan allows 300 emails a day to up to 100,000 contacts, and Starter at $9 covers 5,000 emails a month, AI content tools included.
The limits to watch are the ones on Starter: it stores only 500 contacts at the $9 tier, removing the Brevo logo costs $12 a month extra, and automation and A/B testing wait for Standard at $18 a month. Pick Brevo when your list is large and you email it a few times a month; pick Sender when your list is under 2,500 and you want the biggest free send allowance.
What we like
- Volume pricing suits big lists: $9/month covers 5,000 emails, and the bill follows sends, not contacts
- Free plan sends 300 emails a day with no time limit and stores up to 100,000 contacts
- SMS, WhatsApp, transactional email and a basic CRM sit in the same account
- AI content tools are included on Starter, not held for a higher tier
Watch out for
- The $9 tier stores only 500 contacts, so a bigger list needs a pricier volume tier
- Removing the Brevo logo costs $12/month extra on Starter
- Automation and A/B testing wait for Standard at $18/month
Kit
Best for: Creators and newsletter writers who want unlimited sends and tag-based segmentation
Kit is the creator pick because its free plan has no real rival: the Newsletter plan covers up to 10,000 subscribers with unlimited broadcasts, landing pages and forms, so a newsletter can grow a long way before a bill appears. Creator costs $39 a month for 1,000 subscribers, or $33 a month billed annually, and adds unlimited visual automations and sequences, branding removal and free migrations.
The trade-off is the price jump. Creator is the priciest entry in this list, and it climbs steeply with list size — $139 a month at 10,000 subscribers — while Kit takes 3.5% plus $0.30 on every sale made through Kit Commerce. Pick Kit when you write a newsletter and want the longest free runway for a growing audience; pick MailerLite when you want the cheapest paid plan.
What we like
- The most generous free plan here: up to 10,000 subscribers with unlimited broadcasts
- No sending limits on any plan, free or paid
- Tag-based segmentation fits creators better than list-based tools
- Creator Network recommendations and the Sponsor Network help a newsletter grow
Watch out for
- Creator at $39/month is the priciest entry in this list
- The Creator entry price more than doubled in the September 2025 reprice
- Kit takes 3.5% plus $0.30 on every sale made through Kit Commerce
MailerLite
Best for: Beginners and small teams that want the easiest editor and a free plan that still sends
MailerLite is the easiest tool in this list to run: a clean drag-and-drop editor, landing pages, signup forms and automations that work the way a beginner expects, with support reviewers praise for walking through setup problems. The free plan covers 250 subscribers and 2,500 emails a month with automations included, and Comfort costs $12 a month for 500 subscribers, 5,000 emails, 50 automations and an AI writing assistant.
The free plan is small — it was cut from 500 to 250 subscribers in June 2026 — and Comfort caps sends at ten times your subscriber tier, so heavy senders need Power at $25 a month. New-sender account approval can also be strict and slow. Pick MailerLite when ease of use matters most and the list is small; pick Sender when the free plan needs to stretch further.
What we like
- The easiest editor in this list, with a clean drag-and-drop builder
- Only active subscribers count toward your tier — unsubscribed and bounced contacts are free
- Comfort at $12/month includes 50 automations, 10 landing pages and an AI writing assistant
- Free plan covers 250 subscribers and 2,500 emails a month with automations included
Watch out for
- Comfort caps sends at 10 times your subscriber tier each month
- New-sender account approval can be strict and slow
- Unlimited sends and the deeper automation wait for Power at $25/month
GetResponse
Best for: Senders who want unlimited sends plus webinars, landing pages and a website builder in one bill
GetResponse bundles what the others sell separately: email plus landing pages, and on the higher Creator plan webinars, a website builder and course tools, in one subscription. Starter costs $19 a month for 1,000 contacts with unlimited monthly sends, and the free plan covers 500 contacts and 2,500 emails a month, so a small sender can test the whole workflow before paying.
The limits are in the automation. Starter allows only one custom automation workflow, and the same contact on two lists counts twice toward the contact limit, so the bill can climb faster than the list does. Annual plans are non-refundable, so test on monthly billing first. Pick GetResponse when unlimited sends and bundled extras matter; pick MailerLite when a simpler, cheaper tool will do.
What we like
- Unlimited monthly sends on every paid plan — no send cap to watch
- Free plan covers 500 contacts and 2,500 emails a month indefinitely
- AI content generators included on Starter, with a 14-day premium trial to test them
- Creator adds webinars, a website builder and course tools in the same subscription
Watch out for
- Starter allows only one custom automation workflow
- The same contact on two lists counts twice toward your contact limit
- Annual plans are non-refundable, so test on monthly billing first
Mailchimp
Best for: Senders who want the biggest template library and the most integrations, and email often
Mailchimp is the best-known name here, and the template library and integration list are the reasons: more ready-made designs and more connections to shops, CRMs and form tools than any other tool in this list. Essentials costs $13 a month for 500 contacts and 5,000 sends, with send-time optimization, simple automation flows and 24/7 email and chat support included from the entry plan.
The free plan is the tightest in this list — 250 contacts and 500 sends a month, with no automation flows — and the bill climbs fast with list size, reaching $75 a month for Essentials at 5,000 contacts. Unsubscribed contacts still count toward the tier until you archive them. Pick Mailchimp for the templates and integrations; pick Sender or Kit when the free plan has to carry a bigger list.
What we like
- The biggest template library and integration list in this roundup
- 24/7 email and chat support starts on Essentials, not a higher tier
- Send-time optimization and simple automation flows included from Essentials
- Landing pages and signup forms on every plan, including free
Watch out for
- The bill rises steeply with contacts: Essentials is $75/month at 5,000 contacts
- Unsubscribed contacts count toward your billing tier until you archive them
- Free plan was cut to 250 contacts and 500 sends in February 2026, with no automation flows
Mailjet
Best for: Teams that send marketing blasts and transactional email from one account and want real-time collaboration on templates
Mailjet is the dual-purpose tool in this list: one account sends marketing blasts and transactional email, with an API and SMTP relay on the free plan, so developers can test order confirmations and password resets without paying. The free plan covers 6,000 emails a month and 1,000 contacts, and Starter costs $9 a month for 8,000 emails with no daily cap.
The free plan's flaw is the 200-a-day cap: a blast to 5,000 people takes 25 days to send in full, so it suits drips and small lists, not launch-day blasts. Automation, A/B testing and landing pages wait for Premium at $29 a month, and support quality is the lowest-rated area in its G2 reviews. Pick Mailjet when transactional email shares the account; pick Sender when the blast itself is the whole job.
What we like
- Free plan includes the API and SMTP relay, so developers can test transactional sending at $0
- Paid plans remove the daily cap and include unlimited contacts from Essential, so the bill follows sends
- Real-time collaboration lets a team edit the same template together
- Starter at $9/month undercuts every other first paid plan here except Sender and Brevo
Watch out for
- The 200-a-day free cap means a 5,000-person blast takes 25 days to send in full
- Automation, A/B testing and landing pages wait for Premium at $29/month
- Support quality is the lowest-rated area in its G2 reviews
The best free email blast software lets you send a full-list announcement, promotion or newsletter without paying for the send — and the seven tools below all offer a genuinely free plan, not just a trial. We ranked them by how much you can actually send for free, then by what the first paid plan costs when the list outgrows the free tier, and every price was checked on the vendor's own pricing page on November 6, 2026.
How to choose the best free email blast software
- Measure the free plan in sends, not subscribers. Kit stores 10,000 subscribers free but Brevo's 300-a-day cap and Mailjet's 200-a-day cap decide how fast a blast actually leaves.
- Check the daily cap before launch day. A 5,000-person blast takes 25 days on Mailjet free and 17 days on Brevo free, so a time-sensitive announcement needs a paid plan.
- Count the contacts the free plan excludes. Mailchimp free stops at 250 contacts and MailerLite at 250 subscribers, while Sender covers 2,500 and GetResponse 500.
- Look for automation on the free plan. Sender and MailerLite include automations free; Mailchimp's free plan has none, so a welcome sequence means paying.
- Price the list you will have in a year. Kit Creator is $39 a month at 1,000 subscribers and $139 at 10,000, while Sender and Brevo stay at $9 at the entry tier.
An email list is only useful if people keep finding the signup page, so the list needs traffic behind it. Our monthly SEO service handles the visibility side, and before you publish the landing page the list grows from, run its title through the free SERP snippet preview tool to see exactly how it will look in Google.
Whatever you shortlist, send a real blast before you pay. The free plans in this list are long enough to run one genuine campaign — your list, your subject lines, your send time — and that campaign tells you more than any review can. Check two things in the test: that the whole list receives the blast on the day you meant to send it, and that the open and click reports show up without a paid upgrade. Every tool here lets you export your list, so there is no reason to buy before you have sent from it.
Free email blast software pricing: what you will actually pay
Take a 500-subscriber list that gets one blast a week — about 2,000 emails a month. On the free plans, Sender costs $0, since its free tier covers 2,500 subscribers and 15,000 emails; Kit costs $0, since its free plan runs to 10,000 subscribers with unlimited broadcasts; and GetResponse costs $0, since its free plan covers 500 contacts and 2,500 emails. Brevo costs $0 too, but with a catch: the 300-a-day cap means each 500-person blast takes two days to send, so a Friday announcement finishes on Saturday.
MailerLite and Mailchimp do not fit this list free: both free plans stop at 250 subscribers, so the 500-subscriber list needs Comfort at $12 a month or Essentials at $13 a month. Mailjet fits free on contacts — 1,000 are allowed — but the 200-a-day cap stretches each 500-person blast over three days, so most senders pay Starter at $9 a month to remove the cap.
Over a year, the same 500 subscribers and the same weekly blast cost $0 on Sender, Kit or GetResponse, $97 on Mailjet Starter or Brevo Starter billed annually, $130 on MailerLite Comfort billed annually, and $156 on Mailchimp Essentials, which has no annual discount. The gap between $0 and $156 comes entirely from free-plan caps, not from features — so pick the free plan that fits your list, and only pay when the list outgrows it.
One more cost to check before you commit: Sender's $6.30-a-month annual rate is a first-year discount that renews at $9, so the second year costs $108, not $75.60. And a second audience is a second bill on the contact-priced tools: Mailchimp and MailerLite charge by stored contacts, so a list split across two brands pays twice, while Brevo and Mailjet charge by sends and let the same contacts sit in one account.
Know the difference: email blast software vs email marketing software
The confusion in this category is between a send and a system. An email blast sends one message to a whole list at once — a sale announcement, a newsletter, an event invite. Email marketing software does that too, but adds segmentation, automation and journeys that send different messages to different people at different times. Most tools in this list do both, which is why the same product appears in both kinds of roundup.
There is a second, quieter confusion: a free plan is not a free trial. A free trial ends after 14 or 30 days and then you pay or lose access; a free plan runs indefinitely with limits. All seven tools here have a free plan, so none of them stops working on day 15 — but the limits decide how useful that plan stays. Mailchimp's free plan has no automation flows at all, while Sender and MailerLite include automations free, so two tools with the same "free" label can behave very differently.
A third distinction worth knowing is the daily cap versus the monthly cap. A monthly cap of 6,000 emails sounds generous until the 200-a-day limit means a 5,000-person blast takes 25 days. When a vendor quotes a monthly number, always ask for the daily one too — it is the number that decides whether a launch-day blast actually goes out on launch day.
Quick comparison: tool type by need
| Buyer | Best pick | Why |
|---|---|---|
| Small list, longest free runway | Sender | Free to 2,500 subscribers and 15,000 emails a month, then $9/month |
| Big list, emailed rarely | Brevo | Free 300 emails a day to 100,000 contacts, Starter is $9/month |
| Creator growing a newsletter | Kit | Free to 10,000 subscribers with unlimited broadcasts, Creator is $39/month |
| Beginner who wants the easiest editor | MailerLite | Clean builder and automations on the free plan, Comfort is $12/month |
| Sender who wants extras bundled in | GetResponse | Free to 500 contacts, unlimited sends and webinars from $19/month |
| Sender who wants templates and integrations | Mailchimp | Biggest library in this list, Essentials is $13/month |
| Team mixing blasts and transactional mail | Mailjet | Free API and SMTP relay, Starter is $9/month for 8,000 emails |
Mistakes to avoid
- Budgeting on the monthly cap and ignoring the daily one. Brevo free allows 300 emails a day and Mailjet free 200 a day, so a big blast spreads over days or weeks. Check the daily cap before launch day, not after.
- Picking a free plan your list already outgrew. Mailchimp and MailerLite free plans stop at 250 contacts — a 500-person list pays from day one, so the "free" label costs $13 or $12 a month.
- Paying for sends you could get free. A 500-subscriber list sending weekly costs $0 on Sender, Kit or GetResponse. Do not pay for a plan until the list passes the free tier's contact or send limit.
- Forgetting the annual renewal price. Sender's $6.30-a-month annual rate is a first-year discount that renews at $9, and GetResponse annual plans are non-refundable — read the renewal terms before prepaying a year.
- Splitting one audience across two accounts. Contact-priced tools charge per stored contact, so the same people in two lists cost twice. Keep one audience in one account unless the brands genuinely differ.
How we chose
We checked each vendor's own pricing page on November 6, 2026 — directly for Sender, Brevo, GetResponse, Kit and Mailjet, and against fresh crawls of the pricing pages for MailerLite and Mailchimp, whose pages render prices in scripts — and recorded the starting price exactly as shown, including the annual-billing figure where the page lists one, and we ranked the tools by how much a sender can actually send for free, then by the first paid plan's cost — not by brand size. The chart shows the annual cost of the first paid plan, because every tool here has a free plan and the yearly figure is the honest comparison. All seven G2 ratings come from the G2 review pages opened on November 6, 2026. One correction worth noting: the $17 Mailjet figure that circulates in roundups is its annual-billed monthly rate, not the monthly price — Mailjet's own pricing page lists Essential at $19 a month on monthly billing, and its first paid plan is Starter at $9 a month. No vendor paid for a place in this list, and none of the links here are affiliate links.
What to do next
Start with the free plan of your top pick and send one real blast to your actual list. Check that the whole list receives it on the day you meant to send it, and that the reports make sense before you commit to a year. If the list is sorted but new subscribers are not finding you, our monthly SEO service handles the visibility side — or compare the wider field in our guide to mass email marketing software.

Frequently asked questions
What is the best free email blast software?
Sender is the best free email blast software for most senders: its free plan covers 2,500 subscribers and 15,000 emails a month with automation included, then Standard starts at $9 a month. Brevo is the better pick for a large list emailed rarely, and Kit for creators whose newsletter may grow past 10,000 subscribers.
Is there really free email blast software?
Yes, with limits. All seven tools in this list have a genuinely free plan, not just a trial. The limits are the catch: contact caps from 250 to 10,000 subscribers, send caps from 500 to 15,000 emails a month, and daily caps of 200 to 300 emails on Brevo and Mailjet.
How many emails can I send for free?
It depends on the tool. Sender allows 15,000 emails a month to 2,500 subscribers, Kit allows unlimited broadcasts to 10,000 subscribers, and Brevo allows 300 emails a day. Mailchimp is the tightest at 500 sends a month, and Mailjet caps free sends at 200 a day.
What is the difference between email blast software and email marketing software?
An email blast sends one message to a whole list at once; email marketing software adds segmentation, automation and journeys that send different messages to different people. Most tools here do both, but the free plans differ: Mailchimp's free plan has no automation flows, while Sender and MailerLite include automations free.
Will a free plan hurt my email deliverability?
A free plan alone does not hurt deliverability, but it usually adds the vendor's branding and shares sending infrastructure with other free accounts. Authenticate your domain with SPF, DKIM and DMARC, warm up a new domain gradually, and move to a paid plan with a dedicated sending setup once blasts become regular.
What does email blast software cost after the free plan?
First paid plans run from $9 to $39 a month: Sender, Brevo and Mailjet start at $9, MailerLite at $12, Mailchimp at $13, GetResponse at $19 and Kit at $39. Annual billing drops those to about $97 to $390 a year, except Mailchimp, which publishes no annual discount below 10,000 contacts.
