The verdict

Constant Contact

Best for built-in SMS alongside email

Constant Contact includes SMS marketing (Premium ships 500 messages; lower plans add it from $10/mo), while MailerLite has no native SMS and routes it to sister product MailerSend. Both cover drag-and-drop building, templates, automation, segmentation, and ecommerce, so the deciding edge is texting and email under one roof. The cost: no free plan to start on.

MailerLite

Best for low-cost start with a free tier

MailerLite has a free plan (up to 250 subscribers, 2,500 emails/mo) and paid pricing from $12/mo, where Constant Contact offers no free tier. A/B testing is included on every plan, even free, and it bundles landing pages. The trade-off: no native SMS or transactional email (both go through MailerSend). Best for tight budgets and testing before paying.
