If the From address contains your domain (For example: zylker.com) and the email was generated from Zoho (public.zohoforms.com), the notification emails might be blocked by the recipient domain's anti-spam policy.
You can configure DKIM settings for your account where the inserted Zoho domain in the triggered email would be replaced by your domain (zylker.com) improving the email deliverability.
If you are still facing issues after configuring DKIM settings, please write to us at
support@zohoforms.com.
