12 Best Email Software for Small Business in 2026, Compared

Mailchimp is the safe default in this list because almost everyone has heard of it, and that familiarity pays off: templates, freelancers and how-to guides are everywhere, and more than 300 integrations connect it to shops, CRMs and social tools. Essentials costs $13 a month for 500 contacts and 5,000 sends, with A/B testing, basic automation and 24/7 support included, and the free plan covers 250 contacts and 500 sends a month.

The catch is how fast the price climbs with the list. At 1,000 contacts Essentials costs $26.50 a month, and multi-step automation waits for Standard at $20 a month. Phone support needs Premium at $350 a month. Buy Mailchimp when you want the best-known tool and the widest help available; buy Brevo or MailerLite when the list will grow past 1,000 contacts soon.

Brevo prices by emails sent, not contacts stored, which is the whole reason it sits this high. Starter costs $9 a month for 5,000 emails, and a sender with a big list who emails twice a month pays far less here. The free plan sends 300 emails a day, and SMS, WhatsApp, transactional email and a basic CRM share the same account, so one login covers most small-business messaging.

The catch is the contact cap hiding inside the volume tiers: the $9 tier stores only 500 contacts, so a 5,000-person list needs a higher tier. Removing the Brevo logo costs another $12 a month on Starter, and automation waits for Standard at $18 a month. Buy Brevo when your list is large and your sending is occasional; buy a per-contact tool when you email a small list every day.

Constant Contact is the easiest tool here for a first-time sender. The editor is plain and friendly, event management is built in rather than bolted on, and phone support comes with every paid plan — a rarity in this list. Lite costs $12 a month for 500 contacts and 5,000 sends, with social posting, forms and Canva in the same account.

The trade-offs are the trial and the automation ceiling. There is no free plan, only a 30-day trial with 100 sends, and Lite includes a single automation template, so real automation needs Standard at $35 a month. The price also rises steeply with the list: Lite is $30 a month at 1,000 contacts. Pick Constant Contact when you run events and want a human on the phone; pick MailerLite when you want a free plan and automation included.

MailerLite wins on simplicity: one paid plan carries every email feature, so there is no ladder to climb for landing pages, A/B testing or automation. Comfort costs $12 a month for 500 subscribers and 5,000 emails, and the free plan covers 250 subscribers with automation, landing pages and websites included. The editor is the cleanest here, with three editors and smart sending built in.

The limits are the free plan and support. The free tier stops at 250 subscribers and 2,500 emails a month, and live chat support waits for the Power plan at $25 a month. There is no built-in CRM, so contact management pairs with a separate tool. Choose MailerLite when you want the whole feature set at the entry price; choose HubSpot when the CRM matters as much as the email.

GetResponse is the all-in-one pick because Starter bundles more than email: landing pages, popups, forms and one custom automation workflow sit alongside unlimited sends for $19 a month, or $15.58 a month billed annually, for 1,000 contacts. The free plan covers 500 contacts and 2,500 emails a month, and the AI email writer is included even there.

The catch is the automation ceiling and the pricing page itself. Full marketing automation waits for Marketer at $59 a month, and the page shows promotional annual rates next to the standard $15.58 figure, so read the rate you will renew at. Webinar and course tools also sit on higher tiers. Buy GetResponse when landing pages and unlimited sends matter; buy ActiveCampaign when automation depth matters more.

ActiveCampaign is the automation pick, and the gap is real: multi-step workflows, branching and triggers come on the entry plan, not a higher tier. Starter costs $19 a month, or $15 a month billed annually, for 1,000 contacts and 10,000 sends, with a built-in CRM and more than 950 integrations, the widest in this list. AI features, including an automation builder, are included on Starter.

The trade-offs are the trial and the seat count. There is no free plan, only a 14-day trial, and Starter covers one user, so a second seat needs Plus at $49 a month. The interface also feels crowded until the automation setup is learned. Choose ActiveCampaign when journeys and segmentation are the job; choose MailerLite or Brevo when you mainly send newsletters.

Kit is built for creators, and its free plan shows it: up to 10,000 subscribers at $0, with unlimited forms and landing pages and unlimited broadcasts. The paid Creator plan costs $39 a month for 1,000 subscribers, with unlimited sends, a visual automation builder and the ability to sell digital products and paid newsletters from the same account. Annual billing gives two months free.

The catch is the price once you pay. At $39 a month, Creator is the priciest entry plan here, and visual automation plus advanced reporting wait for Creator Pro at $79 a month. Email design is also plainer than Mailchimp or MailerLite, with fewer templates. Pick Kit when the list is the business; pick MailerLite when a newsletter is one channel among several.

AWeber has served small businesses since 1998, and it still feels built for them: 24/7 live support on every plan, and a 14-day free trial — AWeber has no free tier. Lite costs $15 a month, or $12.50 a month billed annually, and adds AI writing tools and web push notifications.

The limits are the caps on Lite: 3 automations and 3 landing pages, so Plus at $30 a month removes them. There is no free plan — Lite at $15 a month is the entry point — and template design feels dated next to Mailchimp and MailerLite. Choose AWeber when you want a human on call at any hour; choose MailerLite when design polish matters more than support hours.

HubSpot Marketing Hub makes sense when the CRM is the center of the business. Email, forms, live chat and the contact record share one database, so a campaign and a deal never live in two places. Starter costs $20 a month per seat, with a $7-a-seat annual promo for new customers, and the free plan covers 2 users and 2,000 sends a month with no time limit.

The catch is the per-seat math and the automation wall. A three-person team pays $60 a month before the promo, and workflows and sequences wait for Professional at $890 a month — a steep jump. Buy HubSpot when the CRM matters as much as the email; buy ActiveCampaign when you want automation and a CRM at a small-business price.

Zoho Campaigns is the budget pick by a wide margin: Standard costs $4 a month for 500 contacts with unlimited emails, and the free plan covers 2,000 contacts and 6,000 emails a month for 5 users — the biggest free plan by contacts in this list. Standard includes A/B testing, basic workflows and 10 users, and it syncs natively with Zoho CRM.

The trade-offs are polish and depth. Template customization is limited, the interface feels dated, and advanced automation, scoring and dynamic content wait for Professional at $6 a month. Support runs on business hours, not 24/7. Pick Zoho Campaigns when the budget is tight and the business already runs on Zoho; pick MailerLite when design and support matter more.

Moosend is the cheapest way to send often: Pro costs $9 a month for 500 contacts with unlimited sends, and the plan bundles automation, landing pages, forms, A/B testing and an AI writer rather than gating them behind higher tiers. Annual billing drops it to $7 a month. It also carries the highest G2 score in this list, 4.6 out of 5 from 746 reviews.

The catches are the trial and the auto-upgrade. There is no free plan, only a 30-day trial, and going over the contact cap upgrades the account at once and charges the difference immediately. The integration list is also shorter than Mailchimp or ActiveCampaign. Choose Moosend when you send several times a week; choose Brevo when you send rarely and want a free plan.

Omnisend is the ecommerce pick because its automations are built for stores: abandoned-cart, welcome-series and win-back flows come pre-built, and the store syncs deeply with Shopify and WooCommerce. Standard costs $16 a month for 500 contacts and 6,000 emails, with email, SMS and web push in one account, and the free plan covers 250 contacts and 500 emails a month.

The catch is SMS. It needs the Pro plan at $59 a month, so Standard is email and push only, and reporting is shallower than Mailchimp or ActiveCampaign. The free plan is also small at 250 contacts. Pick Omnisend when you sell online and want store automations out of the box; pick Mailchimp when the business is not a store.
