Email Deliverability Best Practices

Getting emails delivered to the inbox (not spam) requires attention to authentication, content, reputation, and sending patterns. This guide covers everything developers need to know.

1. Authenticate your domain

Set up SPF, DKIM, and DMARC for your sending domain. This is non-negotiable for deliverability. AISend's dashboard walks you through the DNS setup in minutes.

2. Warm up your sending

Don't send 100,000 emails on day one. Start with small volumes and gradually increase. AISend's AI handles warm-up automatically by adjusting send rates based on provider feedback.

3. Send relevant content

Transactional emails (receipts, password resets, notifications) have high engagement. Don't mix marketing with transactional on the same domain. AISend's AI scores your content before sending and flags potential spam triggers.

4. Handle bounces properly

Remove hard bounces immediately. Respect suppression lists. AISend automatically tracks bounces and prevents re-sending to addresses that have bounced.

5. Monitor your reputation

Track deliverability metrics: bounce rate, spam complaints, open rates. AISend's dashboard provides real-time analytics and AI-powered recommendations to improve inbox placement.

6. Use a dedicated IP (at scale)

At high volumes (100k+ emails/month), a dedicated IP gives you full control over your sender reputation. Available on AISend's Business plan.
