Overview

 
It Depends on Your Plan

Please note, the Mailgun integration is only available to users on a Basic, Professional, or Custom plan. If you are on a free plan or a free trial and want to upgrade, check out our pricing page or reach out to the Apollo Sales Team for more information.

If you use Mailgun to send high volumes of emails, you can integrate your account with Apollo. This means that you can avoid sending messages directly from your connected mailbox in Apollo to bypass the regular email provider sending limits. As a result, you can send more emails without negatively impacting your domain's deliverability ratings.

Refer to the sections below for the steps to integrate your Mailgun account with Apollo.

 
Location Restrictions

Please note, if you created your Mailgun account with a domain from an EU server, unfortunately, you cannot currently integrate your Mailgun account with Apollo.

Once you have set up a Mailgun account, launch Apollo, click Settings, and then click Integrations under the "Configurations" section on the left.

Making Lemonade Outta Lemons!

Please note, Apollo only automatically pulls in the list of domains from Mailgun when you first integrate Mailgun with Apollo. This means that if you add or delete a domain in Mailgun, the change does not immediately reflect in the list of domains in Apollo. However, no need to panic! If you make any changes in Mailgun, you can click Refresh List. Apollo then refreshes the list as well as the status of the Mailgun webhook in Apollo. Refresh List button

If you try to add or remove a webhook from a domain that no longer exists in Mailgun, Apollo displays an error message.

Error message

 
Whoops!

Deleted the wrong domain? You'll need to reconnect the domain in Mailgun before you can add the Mailgun webhook in Apollo. For more information about how to add and delete domains in Mailgun, hop into this article in the Mailgun Knowledge Base.

 
One Webhook Per Domain

Please note, you can only connect 1 webhook per domain with the Apollo<>Mailgun Integration. If you encounter the error below, you can either delete a non-Apollo webhook from Mailgun or manually add the webhook in Mailgun. Error message 2 For more information about how to add or delete webhooks in Mailgun, please refer to the Guide to Using Mailgun Webhooks in the Mailgun Knowledge Base.
