How to warmup your email domain?

Warming up an email domain is essential when sending emails from a new or inactive domain to build trust with email service providers (ESPs) and improve deliverability. Here’s a step-by-step process to ensure a smooth warmup:

1. Authenticate your domain

• Set up SPF, DKIM, and DMARC Records: These records authenticate your emails, preventing spoofing and phishing. Tools like MXToolbox or PowerDMARC can help validate these records.
• Ensure consistency across DNS settings: A mismatch between DNS records can cause your emails to be rejected or marked as spam.

2. Start with low email volumes

• Begin by sending 10-20 emails per day from your domain. Gradually increase the volume every few days to avoid triggering spam filters.
• Send these emails to known, engaged recipients—like your own team or early contacts—to encourage replies and engagement.

3. Use an email warmup tool or manual approach

• Automated warmup: Tools like Warmup Inbox offer automated solutions that gradually scale your sends while monitoring deliverability.
• Manual warmup: If using a manual approach, prioritize emails that encourage interaction (replies, clicks) to build a positive sending reputation.

4. Engage and monitor performance

• Monitor bounce rates, spam complaints, and open rates using analytics tools or inbox placement monitors.
• If emails bounce or trigger spam filters, adjust your sending strategy and verify email addresses to prevent further issues.

5. Gradually scale sending volume

• Increase volume by about 10-20% every few days. Avoid sudden spikes, as they can raise red flags with ESPs.
• Keep the content clean—avoid spam-trigger keywords and overly promotional language to prevent filtering issues.

6. Track domain reputation and adjust accordingly

• Use tools like Google Postmaster Tools and EasyDMARC to track your domain’s reputation. Make adjustments as needed to maintain a positive reputation.

7. Maintain engagement and hygiene

• Regularly clean your email lists by removing inactive addresses and ensuring all recipients have opted in. High engagement signals to ESPs that your emails are valuable and trustworthy.
