Email Deliverability - FAQs

Email Deliverability - FAQs

1. Why am I unable to add non-organization email addresses in the "To" address?

To add a non-organization email address, the "From" address should not be Zoho Forms' default notification email addressAdding non-organization email address in the To address is available only in our paid plans.

2. Why are my "mailed-by" and "signed-by" domains different, and how can I change them to my own domain?

To change the "signed-by" domain, you'll need to configure DKIM. However, it's important to note that the "mailed-by" domain, which refers to the mail originating domain, cannot be modified. If you still require changes to the "mailed-by" domain, use custom SMTP.

3. What is the maximum attachment size allowed in emails?

The maximum attachment size in emails is 15 MB. If the attachment exceeds this limit, only files within that size limit will be sent.

4. Why are my emails not being delivered from Zoho Forms?

To enhance email deliverability, please ensure that your domain has a DMARC policy configured and that DKIM is configured within Zoho Forms. Read More

5. Why are emails consistently landing in the spam folder?

To ensure emails land in the inbox, it's important to configure DKIM for your domain. If you're sending emails to public domains, configure DMARC for your sender domain.

6. DKIM status is pending even after adding records in the DNS settings. How to fix it?

  1. Re-check whether the values are added properly as a TXT record in your DNS settings.
  2. Verify the correctness of the values by entering the selector and domain name in https://dkimcore.org/tools/keycheck.html.

7.  DKIM has been verified, yet emails continue to land in the spam folder?

To rectify this issue, configure DKIM in Form Settings > General > DKIM & SMTP.

DKIM in settings

Ensure that the domain selected here matches the domain used in the "From" address. This alignment is necessary for DKIM to be effective, thereby improving email deliverability.

8. My email address associated with forms is a public domain email address. How to resolve the email delivery issues?

For public domains such as, yahoo, gmail, outlook, etc., DKIM or DMARC settings cannot be configured. So, you might encounter email delivery issues. This can be resolved by using the  default email address provided by Zoho Forms, notifications@zohoforms.com. This address typically ensures smoother email delivery.

Use default Zoho Forms email addre

9. DKIM has been verified and included in Form settings but my emails are still not being received or are landing in the spam folder.

  1. Review Recipient Server Policies
    Check if the recipient servers have stringent email or spam policies in place, such as content, keyword, attachment, or URL filtering, enforced by their administrators or email service providers.
  2. Test with Blank Email
    Send a blank test email without any content to the recipient's email address to see if it gets delivered to the inbox. If the blank email is delivered successfully, it indicates that the previous emails might have been marked as spam due to their content or attachments.
  3. Revise Email Content
    If the issue seems to be related to the email content or attachments, revise the content and try sending the email again. Avoid using spam-like language, overly promotional content, or suspicious attachments.
  4. Request Recipient Action
    Ask the recipient to mark the email as "Not Spam" if they find it in their spam folder. This action can help train the recipient's email provider to recognize future emails from your domain as legitimate.
  5. Monitor Delivery Status
    Continuously monitor the delivery status of your emails and take necessary actions based on feedback received from recipients.
