Two-Way API Now Available

Less than a minute read

Our developer APIs allow clients to feed information directly into their Sign-Up.to accounts from their in-house databases and data capture mechanisms. We’re now offering a service to advanced API users to keep their in-house databases up to date with subscriber reaction to their email campaigns.

Our new Subscriber Notification API can inform remote systems of email views, links clicked and email forwards performed by campaign recipients. It also issues notifications when we suspend or unsuspend email accounts, and perhaps most importantly, when an email recipient unsubscribes.

Detailed documentation on this service can be found here.
