Although all the tools of Google are very useful, sometimes people face problems while doing their work. Whenever a message or a big file is not sent from Gmail then people get upset and their work gets stuck because it feels bad when you click send and nothing happens. In this article you will find necessary information about the ways to fix email sending issues in Gmail.

How to Fix Email Sending Issues in Gmail Easily

Clear cache

When your mail is not sent then it might be because your browser keeps old files and slows Gmail down. So you need to clear cache or cookies then restart the browser. 

Check net

Also a slow or bad internet makes Gmail fail to send mails or attachments so you should check your Wi-Fi or mobile data. When the net is stable then Gmail usually sends fine.

Blocked type

Some files are blocked in Gmail because they may be harmful. So you need to rename to safe format or choose another file you can attach like PDF or JPG.

Browser issue

Sometimes Gmail in one browser acts slow but works in another because of extension or compatibility issues. If Gmail fails to send, try switching to Chrome.

Ways to Send A Big Attachments

Google Drive

Note that you can send big files by using Google Drive when they are bigger than 25 MB. So you can store them in Drive and insert a link in the mail. 

Compress files

When your file is too big then it is good to make it smaller by compressing because it squeezes data. Then the size may go under 25 MB and Gmail lets you attach it directly. 

Split files

In case your large file is still big even after compressing then it is good for you to split it into parts then attach each in separate mail that is under limit. 

Use cloud link

You can upload files to another cloud like Dropbox or OneDrive then paste a link into Gmail. This way you avoid the attachment limit and the reader clicks a link.

Gmail Customer Support Number

  • Gmail does not have a phone number you can call so don’t look for a number. 

  • Open the Gmail app and use Report a problem to tell Google about your issue. 

  • On the website click the gear icon, choose Help and type your problem.

  • Google will get your feedback and sometimes reply or fix the issue.

  • When you use Google Workspace then you may have access to phone or chat support.

Finishing 

You can easily fix your Gmail message sending problems by clearing cache and checking the internet and when you want to send big attachments then use Drive link or compress so Gmail can send smoothly. Remember that there is no actual gmail customer support number for help so it is best for you to use the Send feedback option inside Gmail to share your issue.
