Hello, we’ve changed the From address to a customized mailaddress from the website domain. However, when the client receives a copy, it states the mail is from ‘email@example.com’ and then the name and customized mailaddress.
How could we remove the ‘firstname.lastname@example.org’ part so that only our customized name and mailaddress show?
The “on behalf of” is added by some mail providers (like Google/Gmail.) That is normally when you are sending from an email address that is not authorized to send through another server. This is a DNS setting with either SPF or DKIM (and possibly DMARC.) Those topics are outside of the support we can offer, but if you have set the FROM address to one address and the email arrives from another, the issue is not with Gravity Forms.

I like Sendinblue these days because they have a free plan with 300 email messages per day allowed. The next closest is Sendgrid with 100 free messages per day.
