Description
Every app that sends email — a password reset, a receipt, a newsletter — depends on that email actually reaching the inbox instead of the spam folder, and mixing "important" transactional emails with bulk marketing sends on the same infrastructure is a common way to tank deliverability for both. MailerLogic is an email platform built for developers that keeps those two email streams separate by design, while also checking every message before it's sent for the kind of content and configuration problems that get domains blacklisted.
MailerLogic bundles a transactional Email API and SMTP relay (drop-in compatible with existing SMTP setups) with a built-in CRM, campaign and marketing-automation tools, and a pre-send deliverability engine that scores content, checks for phishing-style patterns, and verifies SPF/DKIM/DMARC/PTR records before a message goes out. It separates transactional traffic (OTPs, password resets, receipts) from broadcast/marketing traffic to protect sender reputation, and adds bounce-rate throttling with auto-pause to stop a bad campaign from damaging the whole domain's standing. Pricing starts free, moves to $9/month and $12/month tiers scaled by volume, with custom Enterprise pricing for high-volume senders — positioning it as a developer-friendly alternative to services like SendGrid, Postmark, or Mailgun.
💬 Our review
The short version: MailerLogic's real pitch isn't "another email API" — it's separating your password-reset emails from your marketing blasts so one doesn't sink the other, plus a deliverability check before you hit send instead of finding out from a bounce report after.
That stream-separation idea addresses a genuinely common failure mode: teams that route both transactional and bulk mail through the same sending domain and then watch a marketing campaign's spam complaints degrade delivery of critical account emails. Established players like SendGrid and Postmark can achieve the same result with careful configuration, but MailerLogic bakes it in as a default rather than something you have to set up yourself, and bundles a CRM and marketing automation layer on top that those API-first competitors don't offer natively. The tradeoff is that it's a less battle-tested name than SendGrid or Mailgun, so infrastructure-critical, high-volume senders may want to see a longer uptime track record before migrating. Worth trying for a SaaS team setting up email from scratch that wants transactional and marketing mail handled sanely by default; less compelling if you already have a mature, carefully-tuned SendGrid or Postmark setup with no deliverability complaints.
