Link shortening for SMS
ReleasedWe’ve added link shortening for SMS and WhatsApp notifications! Now you can use longer URLs and even tracked links in your messages.

You don’t need to do anything to enable link shortening. It’s enabled by default! Shortened links use the format https://a.cust.io/lnk.abc123
(or https://e.cust.io/lnk.abc123
if you’re in our EU region), consuming between 28 and 38 characters so you have plenty of room to talk to your audience.
