About Email Tools

Email remains one of the most critical communication channels for applications. Whether you're sending transactional emails (password resets, receipts), marketing campaigns, or notifications, a reliable email service is essential for user engagement and retention.

Modern email platforms provide APIs for programmatic sending, SMTP relays, template engines, deliverability optimization, and analytics. Choose based on your volume, deliverability needs, and whether you need marketing features alongside transactional capabilities.

Frequently Asked Questions

What's the difference between transactional and marketing email?

Transactional emails are triggered by user actions (password resets, order confirmations) and are expected by the recipient. Marketing emails are sent to promote products/services. Many providers handle both, but some specialize in one type.

How do I improve email deliverability?

Use a reputable provider, authenticate with SPF/DKIM/DMARC, warm up your sending domain gradually, maintain clean email lists, and avoid spammy content. Providers like SendGrid and Postmark excel at deliverability.
