I host a static website with a number of HTML forms on Netlify. In the Netlify site settings I’ve added the email form submit notifications to go to my email account that works via ZoHo mail.
After about a hunderd submissions I’ve srtopped receiving the emails from firstname.lastname@example.org. ZoHo email support confirmed that emails were rejected by ZoHo Anti-spam filters. Despite the fact that I manually added the email@example.com to the ZoHo spam whitelist. Netlify form emails are filtered out before even going to the Spam folder.
ZoHo representatives are asking me to provide Netlify IP address or IP address range from which firstname.lastname@example.org emails are being sent to my ZoHo email address.
I don’t know where to find those IP addresses. Please help.
