Hi there, @pakaymc,
If you need to edit contacts one by one (the email address change seems a change you can do it as a one-by-one basis), you can select the contact name instead of selecting it with the checkbox (which is indeed more useful for in-bulk based changes).
When you click on the contact name, you should land to the main contact page. Select Contact Actions → Edit contact (first option in the list) and you should be good to go.
Hope that’s all clear! Let me know how you get on!
Hi there, @pakaymc,
Do you have updates about that, do you still need help? We usually close inactive threads after one week of no movement, but we want to make sure we’re all set before marking it as solved. Thanks!
