Improved Email Deliverability
When using Office 365 as an SMTP relay, there are several steps you can take to improve your email deliverability. By following these best practices, you can ensure that your emails are delivered to the intended recipients without getting marked as spam or ending up in the recipients’ junk folders.
1. Use a Custom Domain
One of the first steps you should take to improve email deliverability is to use a custom domain. Instead of sending emails from a generic domain like @outlook.com or @gmail.com, use your own domain for sending emails. This adds credibility to your outgoing emails and reduces the chances of them being flagged as spam.
2. Authenticate Your Domain
Another important step is to authenticate your domain with Office 365. This involves adding the necessary DNS records to your domain’s DNS settings. By doing so, you are proving to email filters that you are the legitimate owner of the domain, which improves the chances of your emails being delivered successfully.
Note: Office 365 provides detailed instructions on how to authenticate your domain. Make sure to follow these instructions carefully to ensure a successful setup.
3. Monitor Your Sender Reputation
It’s important to monitor your sender reputation to ensure that it remains in good standing. Your sender reputation is a measure of how trustworthy your outgoing emails are perceived by email filters. If your reputation falls, it can negatively impact your email deliverability. Office 365 provides tools and reports to help you monitor and improve your sender reputation.
Note: Avoid sending mass emails or spamming your recipients, as this can harm your sender reputation and reduce your email deliverability.
4. Keep Your Email Lists Clean
Regularly clean your email lists to remove invalid email addresses and inactive subscribers. Sending emails to invalid or inactive addresses can harm your sender reputation and trigger spam filters. By keeping your email lists clean, you increase the chances of your emails reaching the intended recipients.
5. Respect Email Best Practices
Follow email best practices to improve your email deliverability. This includes avoiding excessive use of capital letters, including a clear unsubscribe link, and providing valuable content to your recipients. By respecting email best practices, you build trust with your recipients and increase the likelihood of your emails being delivered successfully.
By implementing these best practices when using Office 365 as an SMTP relay, you can significantly improve your email deliverability and ensure that your messages reach the intended recipients’ inboxes.
