In addition to our Google Analytics integration, DonationPay offers a quick and easy way to track donor sources using URL variables.
When you're linking to your donation page, you'll normally link to the page itself using it's DonationPay URL, like https://secure.donationpay.org/YourOrganization/.

(the precise code will be provided by your rep)
The resulting donation will have a custom field, usually called "Source", that's populated with whatever you entered in the URL (in the example, it'd say "EmailCampaign"). Then, in the Portal, you can simply search for "EmailCampaign" to pull up all the donations resulting from this source.
