How to Send Zip File in Gmail on PC or Mac 
Gmail is no doubt the best and most secure email service by Google. It’s completely free to use with up to 15GB of storage and yet very simple to send and receive emails. Though there are some hard limitations with sending attachments, Gmail is not alone in such limits. Other top email clients do have such limits and if you wanna go over the limit, they will stop you from sending such large files. You can only send an attachment of 25MB in size in Google Mail. However, it doesn’t stop you there. Because Gmail has a Google Drive extension to send larger files than 25MB. You can simply upload it to your Google Drive and share it via a link.
Moreover, lots of users do have issues with sending a zip file in Gmail. Because when sending an email with a zip file that contains EXE, DMG, APK, INS, JSE, VDX, BAT, and similar file types. You will notice an error “Blocked for Security Reasons” next to the zip file with a help link. Then you won’t be able to do anything with it but click the “x” option. You don’t have to. Because there is an alternative method you can follow to send any file types via Gmail. I will show you that in the last section of this article.

How to Send a Zip File in Gmail
Sending zip files can save a lot of time instead of adding files one by one into an email. Even on the recipient side, zip file formats can be much easier to save and extract instead of downloading each file one by one. That is where the zip file format comes in handy. It’s a common file format that we can use to compress large or multiple files together into a single one. This way we reduce file size and make it simple to send or store them. Gmail also allows users to attach and send zip files. Here is how to do it:

Go to the location on your PC where you have stored the files. Select all the files or one and right-click. Then click the “Compress to Zip file” option from the menu. The zip file will be generated in the same location. Now rename the file as you like and hit the Enter button on your keyboard. That is it, you have successfully created a zip file and it’s ready to send via Gmail. Now let’s do that:
Go to your Gmail, and click the Compose button under the top left menu. Drag and drop the zip file into the New Message window in Gmail or click the Paperclip icon to attach the file manually. Once uploaded, the zip file in your email is ready to send, click the Send button and you are good to go.
On a MAC
Open the Finder and find the files or folder you wanna create a zip file of. Then select the files or one and right-click. From the right-click menu select the “Compress items” option and in the same location, the zip file archive will be created shortly. You can rename the file as you like. However, it’s ready to send via any email client including Gmail. Let me show you how to send zip files in Gmail on a MAC:
Open Safari or any web browser and go to mail.google.com. Then log in to your account. Now compose a new email. Drag and drop the zip file into the email windows. You can also click the Paperclip icon to attach the Zip file manually. Once you are done composing the remaining email, click the Send button and your zip file will be sent shortly.
