That depends on “what content is in the emails” like whether your emails have images in them as well as text, or if they are just text only emails. So you will need to experiment your end.
If you are trying to sending a lot of emails at once with attachments “and you are restricted in your sending server attachment file size”, then you can alternatively send the attachments “via a cloud drive attachment instead” to reduce the size of the outgoing email using eg: Google Drive, One Drive, Dropbox etc as per the following blog below.
