Hey guys just messing in rails and looking into SMTP email services, now wondering if it's okay to use the GMAIL SMTP service to send email for things like signing up, reset password, confirm account. Or Should i just something like sendgrip or mandrill. from what i can see Gmail seems to allow about 500emails per day. but is it generally a good idea to use Gmail as your SMTP? any advice would be much appreciated. Thanks in Advance!
