MailerSend is the transactional email service from the MailerLite family, known for approachable design, a drag-and-drop template editor, and email verification tools.
MailerSend’s free tier is 500 emails/month; MailBlastr’s is 3,000/month (100/day) with 1,000 contacts, campaigns, and automations included — enough to run a real product pre-revenue.
MailerSend Starter charges $35/month for 50,000 emails. MailBlastr covers the same 50,000 on its entry plan for about 60% less, with 10 domains and 2,500 contacts included.
MailerSend focuses on transactional; campaigns/automation live over in MailerLite as a second subscription. MailBlastr includes campaigns, audiences, segments, visual automations, A/B testing, and polls in the same plan as the API.
Overage on MailerSend bills at $1.30+ per 1,000 automatically. MailBlastr’s prepaid credits cost less per 1,000 and sit in your account until you use them.
If non-technical teammates build most of your templates and you value the MailerLite ecosystem (or need built-in email verification), MailerSend’s editor-first experience is a genuine draw.
The free tier (3,000 emails/month) needs no card — you can run the whole migration before paying anything.
Add your sending domain and follow the guided DKIM, SPF, and DMARC setup. One-click flows exist for Cloudflare, GoDaddy, and Namecheap; verification usually completes in minutes.
Replace your current send with one HTTPS request or a typed SDK in 8 languages. Batch endpoints, idempotency keys, and scheduling are built in.
Subscribe a webhook to delivered, opened, clicked, bounced, complained, and unsubscribed events — every request is signed so you can verify the source.
Bring audiences over via CSV or the contacts API; templates port as plain HTML or rebuild in the block editor.
