May I put a different email address on the landing page than the one I registered with?
That is fine, just remember to check all email addresses related to your registration, if you used a different email address to register vs the one on the landing page, then both those email addresses will be “attached” to your membership.
The one you used to register with, will generally receive communication from us regarding your membership.
The one on your landing page will be visible to potential clients and they will be able to contact you directly via that email address.
Please always remember to regularly check your spam/junk folders as well, for both email addresses, since some SP’s have high-level filters, which automatically send emails to spam.
