Email Setup & Support ​

There could be several reasons why you are experiencing mail delivery failures when sending emails. 

Here are some possible explanations:

1. Incorrect email address: Make sure that you are entering the correct email address of the Gmail recipient. Even a small typo can result in a delivery failure.

2. Spam or filtering settings: Gmail has robust spam filters that may sometimes classify legitimate emails as spam. Check if your emails are being filtered into the recipient’s spam folder. Ask the recipient to check their spam or junk folder for your emails and mark them as “Not spam” if found.

3. Email size or attachments: Gmail has limitations on the size of attachments that can be sent. If you are sending large attachments, they may be rejected by Gmail’s servers. Try sending smaller attachments or consider using a file-sharing service for larger files.

4. Reputation or blacklisting issues: If your email server has a poor reputation or has been blacklisted by Gmail or other email providers, your emails may be blocked or marked as spam. You can check your server’s IP address against popular blacklists to ensure it is not listed.

5. Domain authentication issues: Implementing authentication mechanisms like SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail) can improve email deliverability. Ensure that your domain’s DNS records are correctly configured with these authentication mechanisms.

6. Temporary issues: Sometimes, temporary issues with Gmail’s servers or network connectivity can cause email delivery failures. If the problem persists, you can try reaching out to Gmail support for further assistance.
