EngineMailer — An email delivery platform combining SMTP relay, transactional email APIs, and marketing campaign tools with deliverability monitoring. Here's the fastest sensible path from signup to real value.
Getting started, step by step
- Step 1. Verify your sending domain (SPF, DKIM, DMARC) before sending anything — deliverability starts there
- Step 2. Wire the SMTP credentials or REST API into your app's mailer (for PHP: works as a drop-in SMTP host)
- Step 3. Separate transactional and marketing streams so newsletter complaints don't hurt receipt delivery
- Step 4. Send a seed test to Gmail/Outlook/Yahoo accounts and check spam placement
- Step 5. Watch the bounce dashboard weekly early on; prune hard bounces immediately
One mistake to avoid
Less brand recognition than SendGrid/Postmark — test deliverability to your actual audience domains before migrating everything.
Cost to expect
Plans scale by monthly email volume.
