Unable to send gmail from browser to users with attachments using SMTP

Can anyone please send with snapshots

first the Send SMTP Mail Message is an independent activity - it does not require to open the browser - you can use it straight forward if you have all the required info
Secondly, you may pay some attention on displaying the password on the forum (you could blur or cover that field when you upload screenshots).

Regarding the mailing part using gmail, I am 100% sure there is another topic opened here.

Thanks Theo
I have given correct information in the required fields. And also can you please let me know how to attach files

** Password is wrong in the snapshot attached. Next time while uploading i’ll take care. Thanks
