Email Logs To Easily Diagnose Delivery Issues

When your email fails to deliver, you deserve to know why. Mailgun provides up to 30 days of log retention with all the details of what happened to each message you sent.

An Important Tool for Better Email Delivery

Email messages that get lost in limbo between email servers or have some sort of deliverability issue should not be ignored. Email log files can provide important insights into message delivery, error messages, and the effectiveness of your mass email program overall.

With Mailgun’s email application, every step of the email message journey is logged and indexed, so that you can check the delivery status to the mail server and identify problems with email addresses. Logs are retained for up to 30 days so that you can troubleshoot emails sent, review weekly trends, and figure out how to make improvements all from within your control panel. Having this knowledge base will help ensure that your email program remains robust as you scale.


Why Email Logs Matter

Here are some other reasons that email administrators and developers should take the time to view email logs:


Detect Irregularities

Mailgun’s Managed Services makes it easy to zero in on potential issues by running checks for you. But you can also take a proactive approach by using email logs to review email messages from specific date ranges and time ranges. Then, ask yourself: Are messages bouncing due to incorrect domains or stale addresses? Are their issues with your email templates? Are error codes popping up? If you view email logs regularly, you can more effectively use your email application to solve the problems.

Protect Your Sender Reputation

You don’t want to be known as a company that sends spam or get blocked by Google/Gmail. Protecting your IP address and domain starts with staying in tune with your email logs. Regularly searching logs for delivery failures is a great way to monitor your account for performance issues. This will keep your list clean for your next send so you don’t end up hurting your reputation or, worse, getting blacklisted. Which if ever concerned, check your email sender reputation regularly to always keep notice of.

Avoid high-risk recipients

Quickly Search Emails Sent

If you need to locate something specific, it can be hard to sift through hundreds of search results if you don’t have a good email log. Mailgun’s cloud email application makes it easy to search across your email account by filtering numerous messages via a large number of possible values including:

  • the to and from email addresses
  • event type
  • list name
  • tag name
  • message ID
  • subject line
