Troubleshoot Comcast Email Not Sending Emails
Now, it’s time to rectify these causes one by one. The fixes you need to follow are extremely simple yet effective.
1. Set Up Your Comcast Account Correctly
To use your Xfinity email account via a third-party mail client such as Outlook, you must set it up in the correct way. Head to the official Xfinity website and find the instructions to configure your email according to the third-party program you use. If you don’t find your program listed, follow these settings.
- The incoming server name must be imap.comcast.net.
- 993 is the incoming port number.
- SSL is always on.
- The authentication method is STARTTLS.
- 143 is the port number, and SSL is on.
- The outgoing server name must be smtp.comcast.net.
- Its server port number is 587 or 465.
- The encryption method is TLS. If it is not there, use SSL.
- For authentication, enter your Comcast.net email ID.
2. Examine The Recipient’s Email Address
Although it may seem insignificant, people often misspell the email ID of the recipient. This hinders them from successfully sending an email from their Comcast account. If you are unable to send Comcast emails to a specific recipient, double-check the email ID you are typing. It should be fully correct.
At the same time, examine whether you haven’t mistakenly blocked the recipient. It will also make you unable to send a message from your account. If you find the recipient’s email ID among your blocked contacts, unblock it from the settings of your email.
3. Inspect The Spam Folder
The spam filter issue prevents your email from getting sent. If the spam filter that you have set is causing problems in sending and receiving emails, disable it.
The process of doing so is easy. Just log into your Comcast account with the right credentials. Now go to ‘Users and Preferences’ and tap the ‘Edit’ button. It is present on the ‘Spam filter’ option. Now select the ‘Disable spam filter’ option and tap ‘Save.’
4. Delete And Re-Add Your Email Account
Sometimes, the third-party program linked with your Comcast email account has a glitch. It results in Comcast not sending emails. A good way to troubleshoot it is to delete your account on the mail client and re-add it. But remember to back up your local folders before deleting your account.
- Sign into your Comcast account.
- Now, head to the ‘Emails’ tab.
- After choosing the Inbox folder, tap the icon beside it.
- In the menu, choose to delete all messages.
- You must also delete the account on the mail client and then choose the ‘Auto configure’ option to add your login credentials.
5. Clear Out Cookies And Cache
You won’t be able to deliver messages from your Comcast email if there are a large number of cookies and caches in it. So, emptying these things will allow you to restore the functioning of your Comcast email.
Just head to the browser settings and eliminate cookies and cache from there. After emptying them, check if you can send an email.
6. Find if You Have Gone Past The Sending Limit
You must be aware of the email sending limitations of Comcast. A message can be sent to not more than 100 recipients in a single day. Xfinity subscribers can send messages to 1000 recipients in one day. If you go beyond this limit, you will find yourself unable to send Comcast emails. They won’t be delivered to your recipients.
7. Check if The File You Are Sending Is Too Large
You cannot send an email of over 25 MB in Comcast. This size comprises headers, attachments, formatting, and text, among others. But if you really need to send a file that big in size, here are two options for you.
- Upload the email attachment to the webspace. Let your recipient download it from this place.
- If you are sending a text file attachment, it is better to zip the file before attaching it. It’s possible to compress files in various formats such as .XLS, .DOC, .BMP, .TXT, and .PPT. Ensure that your recipient knows how to access them. Similarly, if you are sending pictures as attachments that are in .BMP or .GIF format, convert them to .JPG.
8. Eliminate Problematic Browser Plugins And Extensions
Sometimes, the plugins and extensions you have installed on your browser interfere with the working of Comcast email. It’s possible that you cannot send emails because of them. So, examine all the plugins and add-ons and keep only those you need the most. After that, check whether you can send emails.
