What to look for
- Total cost at your subscriber count — many tools are cheap at 500 contacts but expensive at 5,000
- Do they charge for unsubscribed contacts? Mailchimp and ActiveCampaign do, MailerLite does not
- How steep is the learning curve? You probably do not have a dedicated marketing person
- Deliverability rates from independent testing — not the platform's own claims
- What happens if you need support? Check Trustpilot ratings for real support experiences
Quick Picks
How They Compare
MailerLite is easy to learn and scored 89.8% in EmailToolTester's January 2024 deliverability round. Free includes up to 250 subscribers and 2,500 emails per month. Comfort starts at $12/month and Power starts at $25/month. Subscriber-tier pricing varies; verify the live quote before making a cost comparison. Its strict account-approval process is an important operational risk, so review eligibility and export your list regularly.
Brevo's unlimited-contacts pricing model is uniquely valuable for small businesses with larger lists but moderate sending frequency. Instead of paying per subscriber, you pay per email sent — starting at $9/month for 5,000 emails. A business with 5,000 contacts sending twice a month pays a fraction of what Mailchimp charges. The trade-off: the interface is less polished than MailerLite, and the free plan caps you at 300 emails/day.
GetResponse offers a strong middle ground between MailerLite's simplicity and ActiveCampaign's power. At $19/month for 1,000 contacts, you get email marketing, landing pages, webinars, and decent automation. It's particularly good for small businesses that run webinars or need built-in landing pages without paying for a separate tool. Deliverability sits at ~85.5% — solid but not market-leading.
Kit (ConvertKit) is the creator-focused option. If your small business is content-driven — a blog, online courses, a newsletter — Kit's tag-based subscriber management and clean email editor are excellent. The free plan covers 10,000 subscribers (the most generous limit of any platform), but automation is limited to 1 sequence until you pay $33/month.
Mailchimp still has the largest integration ecosystem (300+ apps) and the most recognizable brand. If you rely on niche tools that only connect to Mailchimp, or your team already knows the platform, there is a case for staying. But the pricing premium (36-63% more than MailerLite at every tier), middling deliverability (78.35% inbox placement), and charging for unsubscribed contacts make it a hard sell for cost-conscious small businesses.
