Note: Bear in mind that not all email service providers (ESPs) permit affiliate links in email. Be sure to read your ESPs' policies surrounding affiliate links before sending them directly in email.
Note also that Amazon does not permit sending their affiliate links via email. In these situations, you should send your readers to a page on your website which then links to Amazon.
There are two main scenarios for attributing email-driven affiliate revenue:
Here's how you can attribute each with Affilimate's help.
Tracking affiliate links directly in email
For links directly inside an email or newsletter, you need to create a unique SubID (AKA Tracking Label) for each affiliate link included in the email.
A SubID (also called a Campaign ID, Tracking ID, TID, SID, etc.) is part of an affiliate link that helps you identify where the sale came from. Here's an example:
For example, if your email campaign is called "Black Friday Deals" then you should create a unique SubID for each email link such as "black-friday-deals -email".
Note that the exact parameter (in the example above, "subid=") will vary by platform.
When using each platform's affiliate link builder, you'll be able to specify the exact SubID according to that platform's requirements.
Finally, when you import those commissions in Affilimate, you'll see "black-friday-deals-email" next to the product name and commission amount.
For example, if you end all your in-email SubIDs with "-email", you'll be able to search by that to determine your email revenue:
Links from email to affiliate content on your website
As of today, you cannot tell which of your affiliate commissions came from Email as the traffic source, but it's something we plan to add in the future.
In general, when linking to your website from an email campaign, always include the utm_medium as "email" and utm_campaign as the name of your email campaign, such as "black-friday-deals".
For example, if linking to Wirecutter's homepage, your link would look like https://www.nytimes.com/wirecutter/?utm_medium=email&utm_campaign=black-friday-deals.
This will help you identify Email traffic to your site in Google Analytics.
