GMail have increased the size of attachments they will allow you to send on their email service from 20Mb to 25Mb. This increase is good news and allows you to send slightly more when and if needed.
The only limits you really need to look out for now are limits on receiving end of your email. If the receiver allows less to be received then your sent message will bounce back. That shouldn’t be too much of a problem to be honest these days as inbox’s can usually take a hefty amount of email and a nice sized attachment size.
