This means if the sender is using any other email service, the Gmail user will be able to receive the files of up to 50MB in size, while the sending limit from a Gmail account will remain the same.
Before now, receiving large attachments through Gmail was virtually herculean. However, Google has kept the outgoing email attachment size limit at 25MB.
Google's still very much wedded to the idea of people using Google Drive for large files, but it recognizes that many workplaces and individuals are yet to make the switch to Gmail and Gsuite. However those files weren't really attached, and were mostly just links for the recipient to download the file. You pop into your gmail all fired up to send it but alas, the video exceeds the 25 MB limit put up by Google. However that is only for incoming email.
Please note that the new file size is applicable only for Gmail users and only for incoming mails for now. "While Google Drive offers a convenient way to share files of any size, sometimes you need to receive large files as direct email attachments", Google said in a blog post. Your storage limit starts at 15GB (which includes Google Drive and Google Photos, technically it's 5GB each), and you can add more from there. Annoyingly, the maximum size for an outbound attachment is still 25MB. According to the post, all the users should see the revised receiving limit in 1-3 days.
