Email marketing has the best ROI of any digital channel — $36 back for every $1 spent, according to Litmus. But only if your emails actually land in inboxes, and only if you're not overpaying for a platform built for enterprise teams. We tested 8 platforms on deliverability, automation quality, and real pricing.
Quick rankings
- Kit (ConvertKit) — Best for creators and content businesses
- Brevo — Best value for volume senders
- ActiveCampaign — Best automation for complex workflows
- Mailchimp — Best brand recognition, mediocre value
- MailerLite — Best budget option
- Flodesk — Best design, limited analytics
Kit — Best for creators
Kit (formerly ConvertKit) is built around the creator economy — newsletters, courses, memberships. The automation is visual and genuinely intuitive. Subscriber tagging and segmentation are first-class features, not add-ons. Free plan covers up to 10,000 subscribers.
Pricing starts at $9/month for up to 300 subscribers (paid plan removes Kit branding). Scales reasonably as you grow.
Brevo — Best value for high volume
Brevo (formerly Sendinblue) prices by email sends, not subscriber count — a key difference. If you have a large list but send infrequently, Brevo is dramatically cheaper than Mailchimp. 300 emails/day free forever. Paid starts at $25/month for 20,000 sends/month.
Deliverability is solid. Automation is capable if not as polished as ActiveCampaign. SMS marketing is built in.
ActiveCampaign — Best automation
If your marketing strategy relies on behavioral triggers, conditional logic, and multi-step sequences, ActiveCampaign is the most capable platform in this price range. The automation builder is genuinely powerful. Starts at $15/month (Starter, 1,000 contacts), but the features most teams want are on Plus ($49/month).
Mailchimp — Overhyped, still decent
Mailchimp is the most recognized name and probably the platform you should use if all your team members need to collaborate without training. But the pricing is among the worst value in this category. Their free plan was cut to 500 contacts in 2023. The Essentials plan ($13/month) removes key features like A/B testing. You'll likely end up on Standard ($20/month) faster than expected.
MailerLite — Best budget option
MailerLite offers 1,000 subscribers free (with 12,000 sends/month) and paid plans starting at $9/month. The automation is surprisingly capable for the price. Good for small businesses just starting email marketing who don't want to think about it too hard.
What to look for in 2026
- Deliverability rate: Ask your shortlist for their average inbox placement rate. Good platforms publish this.
- Pricing model: Per-subscriber (Mailchimp, Kit) vs. per-send (Brevo) matters significantly depending on your list behavior.
- Automation complexity: If you're doing simple newsletters, any platform works. If you're building sales funnels, invest in ActiveCampaign or Kit's paid automation features.
