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; SendDart’s is 3,000/month (100/day) with unlimited stored contacts, campaigns, and automations included — enough to run a real product pre-revenue.
MailerSend Starter charges $35/month for 50,000 emails. SendDart 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. SendDart 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. SendDart’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, 100/day) needs no card — enough to verify the whole migration end to end before paying anything.
Add your sending domain, copy the DKIM, SPF, and DMARC records into your DNS provider, then click Verify in SendDart. Allow for DNS propagation before testing delivery.
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.
The send call, after the switch
curl -X POST https://www.senddart.com/api/emails \
-H "Authorization: Bearer mb_xxxxxxxx" \
-H "Content-Type: application/json" \
-d '{
"from": "Acme <hello@acme.com>",
"to": ["delivered@test.senddart.com"],
"subject": "Welcome to Acme",
"html": "<p>You are in.</p>"
}'The sending domain is taken from the address in from — there is no domain field on this endpoint. delivered@test.senddart.com is the test recipient that reports a delivered outcome without sending real mail.
