Email API with built-in deliverability intelligence
MailerLogic is a modern alternative to SendGrid, Mailgun, and Postmark. Send transactional and marketing emails via SMTP or API with built-in stream separation and deliverability intelligence. Analyze health, engagement, risk, and content quality before sending. Includes CRM, automation, campaigns, and 260+ APIs. Send emails and make sure they land.
MailerLogic started as an internal email system for our LMS. Over time, we realized most tools focus only on sending emails, but not on why emails fail.
The real problems we faced were:
👉 Why are emails going to spam? 👉 Why is domain reputation dropping? 👉 Why is deliverability inconsistent?
So we built MailerLogic as a full email infrastructure platform, not just a sending service.
It combines an ESP like SendGrid, Mailgun, and Postmark, a flexible email-first CRM, and built-in deliverability diagnostics all in one place.
🔍 Instead of fixing issues after sending, MailerLogic helps you:
Analyze health score, engagement score, and deliverability test score
Run risk assessment and content quality checks
Monitor domain reputation in real time
Manage contacts, segments, tags, and custom properties through API
Build automations and marketing funnels directly into your workflows
💡 Who it’s for:
SaaS platforms sending transactional and bulk emails
Developers building email workflows and integrating email infrastructure via API
Marketers running campaigns who care about inbox placement
Teams that need a fully API-driven CRM with contacts, segments, tags, and custom properties
Businesses building automations and marketing funnels directly into their workflows
SaaS platforms looking to embed white-label email delivery into their product with full control over domains, branding, and deliverability
Start free and test campaigns, automations, and deliverability tools right away.

Who hunted MailerLogic?
MailerLogic was hunted by Yasin Rahim. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
