Attachments issues
A list of all warnings you may encounter when sending an email with attachments.
Here is a list of common messages of error or warning you may get using attachments:

File is too large

A file cannot exceed 4 MB in size as an attachment. If you get a warning "File is too large" we can recommend you to lower the size of your file. You can either:
Although Gmail allows uploading file up to 25 MB, the limit allowed during mail merge sending is different. To avoid taking too much time during sending, a size limit of 4 MB is imposed.

The total size of attachments is too large

The total sum of your attachments size cannot be more than 4 MB. To lower the size of your files, you can try to compress them, create an archive (.zip) or host them online and link to the folder.

Too many attachments

You can add up to 10 attachments to your email merge. If you need to send more files, you can try to create a .zip. But, we recommend you to add a link to a Google Drive folder, which gives a lot more flexibility on the number of files and size.

Blocked for security reasons

To protect your account against potential viruses and harmful software, Gmail doesn't allow you to attach certain types of files.
List of blocked file extensions: .ade, .adp, .apk, .appx, .appxbundle, .bat, .bz2, .cab, .chm, .cmd, .com, .cpl, .dll, .dmg, .exe, .gz, .hta, .ins, .isp, .iso, .jar, .js, .jse, .lib, .lnk, .mde, .msc, .msi, .msix, .msixbundle, .msp, .mst, .nsh, .pif, .ps1, .scr, .sct, .shb, .sys, .vb, .vbe, .vbs, .vxd, .wsc, .wsf, .wsh
