If your emails are being marked as spam or experiencing poor deliverability, follow these steps to diagnose and resolve the issues:

1. Check Your Email Deliverability with SendForensics or MXToolBox

Start by analyzing your current email reputation and deliverability status:

• Visit SendForensics (sendforensics.com) and run a comprehensive deliverability test

• Review your sender reputation scores across major email providers

• Check for any blacklist issues or authentication problems

• Identify specific deliverability issues that need to be addressed

• You can also head over to MXToolBox (link) and place your domain URL and see if your domain is listed in any of the spam domain listings.

2. Pause Your Campaigns for One Week

Give your email reputation time to recover:

• Immediately pause all active email campaigns in Overjoy

• Use this break to implement the fixes identified in step 1

• Monitor your domain reputation during this recovery period

3. Lower Your Sending Volume When Restarting

Gradually rebuild your sending reputation:

• Start with 25-50% of your previous daily sending volume

• Gradually increase volume by 10-20% each week if deliverability improves

• Focus on engaging your most active subscribers first

• Monitor bounce rates and spam complaints closely

4. Diversify Outreach with Multiple Sender Emails

Reduce risk by spreading your email volume across multiple addresses:

• Set up 2-3 different sender email addresses on separate subdomains

• Distribute your email campaigns across these different senders

• Use different email addresses for different types of campaigns (newsletters vs. sales)

• Ensure each sender email has proper authentication (SPF, DKIM, DMARC)

5. Warm Up New Email Accounts

Build reputation for new sender addresses:

• Use email warming services like Mailwarm, Lemwarm, or Warmup Inbox

• Start the warming process 2-4 weeks before using new addresses for campaigns

• Gradually increase the warming volume over time

• Monitor the reputation scores of your warming email addresses

Additional Tips

• Clean your email list regularly to remove inactive or invalid addresses

• Create engaging subject lines and content to improve open rates

• Always include an easy unsubscribe option

• Monitor your analytics closely and adjust your strategy based on performance

By following these steps systematically, you should see significant improvements in your email deliverability within 2-4 weeks.
