I want to send an upgrade email to a user base and last time I used something like this inside the email:
To upgrade follow this link: http://www.mysite.com/upgrade.php?user=[EMAIL]_[ID]
Later I noticed some people had problems with the link because certain email clients would lift the/an email out of the link to make it a sendto: hyperlink, which was not the intention.
Is there a Filter that can be applied on the fly somehow to change [EMAIL] ?
For instance replace the @ with ~at~ or something like that ?
My php can then of course reassemble the email address.
If not I can export a list, import in excel, change the email address and add a new attribute, e.g. [EMAILFORLINK] but that’s a step that possibly can be avoided ?
