9 Reasons Why Your Emails Aren’t Delivering

Subscribe to email updates

It can be extremely frustrating when you’re working and realize that your emails are not delivering. If you are unable to send emails, it could be for a variety of reasons but the good thing is – we deal with this kind of issue often and we can tell you about the common reasons why this might be happening.

Most likely we find the issue is that your email provider cannot connect to your mail server.;We’ve provided the top reasons why this issue might be happening below, check it out!

1. Bad Passwords

You have to create a new password every so often for security purposes. A part of this is remembering your old passwords and constantly creating new ones. If your password has expired, this might be one of the reasons why your emails aren’t sending. Either change your password or reset your password. If you forgot your current password, reset the password and your admin will send you a new temporary one.

2. Network Connection Errors

When mail servers crash there are a couple of things you can do to fix the issue. First go to the control panel and restart the service. By doing this, you will most likely fix the connection. If your connection does not work, this may be a DNS problem in which case you need to check your DNS connection. Sometimes this issue can be as simple as the name not matching the actual name of the DNS. If the issue still persists, contact your ISP or network administrator to ensure that you are on the right setting.

 

3. ISP Blocks Email Ports

You need an email “port” AKA the Simple Mail Transfer Protocol (SMTP) to be able to send emails. Unfortunately AND fortunately, some ISP or network providers will block specific ports so they can prevent viruses from sending out thousands of spam emails to people. Good for others, bad for you at the moment. We understand. To check if your ISP is blocking the port you want to use on this website.

4. SMTP Authentication Settings

First, is your network using a VPN? Have you had any power outages? Sometimes when these two things happen, your IP address will change causing your IP to look “fishy” therefore your emails won’t send. To fix this issue in your email you need to go to SMTP settings and choose the appropriate authentication method to your SMTP server. If you’re having issues finding this, contact your administrator or contact us. If you don’t have an IT professional, we can help you.

5. SSL Connection Settings

SSL or “Secure Sockets Layer” is the security between your web browser and your server. Normally whichever email account provider you are using will support your SSL for your outgoing mail server (the SMTP that we talked about earlier). If your emails aren’t sending out you may need to connect the mail server using SSL. If you still get an error message, make sure to deselect your options and contact your email administrator.

6. Email is offline

A common issue to not being able to send emails is that your email is offline. There are many ways to fix this issue depending on your email provider. But the basic premise is to take your account online. If you’re using Outlook, you may see the message in the bottom right hand corner of your application window. For Apple, you’ll see a lightning bolt in your favorites bar and take your account online. 

7. Did you let your file upload before you sent the email?

It can be easy to click “send” right once you attach a file. Wait until the file loads until you send. If the file is too large there are a couple of different ways you can send the file. Try uploading the file to a online storage provider like Google Drive, OneDrive, Box.com, or DropBox. Then send the recipient the link and they can download the file.

8. Undeliverable

There are a couple of different reasons that your mail make come back as undeliverable. Here are some possible solutions: check if the email you entered is correct, reduce the number of recipients that are receiving the email, or try using the web address of the mail provider you are using – for example, go to outlook.com and try and send the email.

9. Mailbox size

Sometimes email providers won’t receive emails if their mailbox is full or memory is full. First, find another way to contact the recipient to let them know. Then, start deleting emails or enable automatic deleting of the archived emails you don’t need anymore.
