If you're running a WordPress website and using plugins that send emails (like contact form plugins, email marketing tools, or notifications), you'll want to make sure those emails don't end up in your recipients' spam folders. Getting marked as spam can severely hurt your email deliverability and communications. Here are some tips to avoid the spam trap with your WordPress plugin emails:
- Authenticate Your Emails Many spam filters check if emails are authenticated using protocols like SPF, DKIM, and DMARC. Configure these for your WordPress site to verify you as a legitimate sender.
- Avoid Spammy Content Carefully review the content and formatting of your emails. Avoid anything that might seem spammy like excessive uppercase letters, lots of symbols/numbers, or too many links.
- Warm Up Sending Volume If you're suddenly sending lots of emails from a new IP address, it can trigger spam filters. Gradually increase your sending volume over time.
- Maintain Good List Hygiene Only email people who have opted-in to receive emails from you. Remove inactive subscribers periodically. High bounce/complaint rates can hurt deliverability.
- Monitor Blacklists Check reputational blacklists like Spamhaus and get delisted if needed. Use an email testing tool to identify any issues deliverability issues.
- Consider a Dedicated Email Service For higher volumes, it may be worth using a robust email service provider optimized for email deliverability.
