MailerSend
MailerSend is a transactional email API and SMTP service; mailersend.com served the product homepage directly when we verified it in August 2026. It sits in our transactional protocol line alongside the other API-first senders.
With the volume slider at the 50,000-email step, Starter costs $35/month billed monthly ($31.50 billed annually), including 10 domains, 50 webhooks, and logo removal; overage is $1.30 per 1,000 emails, and a dedicated IP is enterprise-only. A free plan sends 500 emails per month, and the $7 Hobby tier covers 5,000. Pricing checked 19 August 2026.
Deliverability: not yet tested. A measured seed-list cycle for MailerSend is planned as part of our catalog rollout — see how we test for the protocol and the email deliverability ranking for services with data.
