To ensure accurate email event tracking when you integrate Apollo with SendGrid, you must configure the event webhook settings in Apollo. To do so:

  2. Apollo populates the HTTP Post URL field, configures the necessary event types and tracking options, and enables the webhook authentication toggle for you. Populated webhook event settings

SendGrid and SPAM Filters

SendGrid replaces the tracking URLs and directs them to SendGrid servers to resolve deliverability issues. If you connect your Apollo account to SendGrid, you do not need to configure a Tracking Subdomain because SendGrid manages your tracking links on their end. For additional information, please see the "Set Up, Configure, and Troubleshoot Your SendGrid Account" article.

SendGrid and SPAM Filters

Please note, if your emails are flagged as SPAM when your Apollo account is connected to SendGrid, you may need to replace the tracking link in the emails within your SendGrid account itself. SendGrid includes a feature called Link Branding that functions the same as Apollo's Tracking Subdomain. This Link Branding feature provides the URL that you must replace to reset the deliverability on your account. In this scenario, contact SendGrid Technical Support so that they can help you update this configuration and provide any additional information about deliverability within your account.

For more information about SPAM filters, please read the "Avoid SPAM Filters" article.

Which SendGrid Plan Do I Choose?

The Apollo integration works with all SendGrid plans, so the world is your oyster! You can connect your SendGrid account with Apollo whether you have an Email API plan or a Marketing Campaigns plan. This includes free or paid plans.

However, please note that if you are on one of their free plans, SendGrid limits the number of emails you can send per day and month. For more information about SendGrid pricing, sneak a peek at the SendGrid pricing page.

For Old-Timers Only!

Please note that Apollo only recommends integrating with your SendGrid account if you already actively use their platform for transactional or marketing emails. If you don't, consider using this Apollo partner to help you follow deliverability best practices.
