Why we chose it

Mailchimp balanced everything: top-three inbox placement, the easiest campaign builder, and reporting a small team can act on without a data analyst.

Keep in mind

Pricing rises with contact count — including unsubscribed contacts unless you archive them.

02

Brevo

Best value — pay per send, not per contact
  • Priced by emails sent, not list size — huge lists stay cheap
  • SMS and WhatsApp campaigns built in

Why we chose it

Brevo's send-based pricing flips the economics: a 50,000-contact list that mails weekly costs a fraction of contact-based rivals, with automation included.

Keep in mind

Template selection is smaller than Mailchimp's, and the daily cap on the free plan is tight.

03

ActiveCampaign

Advanced automation journeys
  • The deepest automation builder we tested
  • Behavioral triggers, lead scoring, and split paths
  • CRM included on higher tiers
9.1

Why we chose it

No platform matched ActiveCampaign's automation canvas — our seven-branch onboarding journey with lead scoring took an afternoon to build and ran flawlessly.

Keep in mind

Power comes with complexity; beginners face a real learning curve.

04

Klaviyo

E-commerce revenue attribution
  • Deep Shopify and WooCommerce integrations
  • Revenue-per-email reporting out of the box
  • Predictive analytics for churn and next order

Why we chose it

Klaviyo is the e-commerce specialist: its Shopify/WooCommerce integrations and revenue-per-email reporting directly connect campaigns to sales, and its predictive analytics (churn risk, next-order date) actually inform strategy.

Keep in mind

Pricing climbs quickly with list size, and it's more platform than most non-commerce senders need.

05

Constant Contact

Nonprofits, events & beginners
  • Event invitations and RSVP tools built in
  • Strong nonprofit discounts
  • Phone support on every plan
8.5

Funnels, webinars & landing pages
  • Webinars included — rare at this price

Why we chose it

GetResponse bundles webinars, landing pages, and conversion funnels with email — the only platform here where a full lead-gen funnel needs no third-party tools.

Keep in mind

Doing many things means email-specific polish (deliverability tooling, template depth) trails the specialists.

How to choose the right email marketing in 2026

Key insights

  • Mailchimp remains the best all-round platform for small businesses in 2026
  • Brevo's pay-per-send pricing is the money-saver for large, low-frequency lists
  • Deliverability varies more than features — it decides whether emails get seen at all
  • Automation flows (welcome, abandoned cart, win-back) drive most email revenue
  • Archive unsubscribed contacts — most platforms bill for every stored contact

What we evaluate

  • Deliverability — measured inbox placement at Gmail, Outlook, and Yahoo — not vendor claims
  • Automation depth — triggers, branching journeys, and scoring without engineer help
  • Pricing model — per-contact vs. per-send economics at YOUR list size and frequency
  • Builder & templates — fast, on-brand campaigns without fighting the editor
  • Reporting — revenue attribution and engagement metrics that guide decisions

How much does email marketing software cost in 2026?

Free plans handle up to 250–500 contacts. Paid entry tiers run $9–$20/month and scale with list size — a 10,000-contact list typically costs $75–$120/month on contact-based pricing. Two cost levers matter: archive inactive contacts (most platforms bill for every stored address), and if you mail a big list infrequently, Brevo's per-send model can cut the bill by half or more.

Which email automations actually make money?

Three flows generate the bulk of email revenue for most businesses: the welcome series (highest open rates you'll ever see), abandoned-cart recovery for stores, and a re-engagement/win-back sequence that also protects deliverability by pruning dead addresses. Build these three before spending any time on clever campaign ideas — in our testing they took under a day combined on Mailchimp or ActiveCampaign.

Bottom line

Mailchimp for most businesses, Brevo for per-send savings on big lists, ActiveCampaign for serious automation, Klaviyo for stores, Constant Contact for events and nonprofits, and GetResponse when you want funnels and webinars in the same bill.

Email Marketing FAQs

Mailchimp is our top overall pick for its balance of deliverability, ease, and integrations. Brevo wins on value, ActiveCampaign on automation depth, and Klaviyo for e-commerce.

Brevo's free plan (300 emails/day, unlimited contacts) suits small lists that mail often; Mailchimp's free tier (500 contacts) is the easiest full-featured starting point.

Most small businesses land between $13 and $50 per month. Given email's consistently high ROI benchmarks, the platform fee is rarely the constraint — list quality and consistency are.

Across industries, 35–45% is healthy post-Apple-privacy-changes; click rates of 2–4% are typical. Trend direction on your own list matters more than industry averages.

Once you send at volume, yes — authenticating your own domain (SPF, DKIM, DMARC) meaningfully improves deliverability, and Gmail and Yahoo now require it for bulk senders.
