User is not unsubscribing when having + in the email

Question

Facing an issue, I noticed some cases where users are unable to unsubscribe if they have a + symbol in the email address.

Example - abc+cd@gmail.com

Does anyone have the same issue before? any idea why this is happening?

Answer 1

It happens because + equates to a space when the email address is URL encoded.

Your custom preference center will need to be updated to replace all spaces with + characters.

SSJS:

emailAddress = emailAddress.replace(" ","+");

AMPscript:

set @emailAddress = replace(@emailAddress," ","+")
