Speed has never been one of GMass’s strengths. Until now.
If, for example, you need to send 1 million emails in an hour, then GMass isn’t the right software for you. If, however, speed can take a backseat to optimal deliverability, then GMass is likely a winner for you.
There are two ways to send with GMass — natively through your Gmail account, or via a third party SMTP service like Sendgrid. In both cases, GMass “acts” like you’re sending the emails directly from your Gmail account. All emails show up in your “Sent Mail” folder, so they can be searched, and you can still use auto follow-ups.
We have now introduced a way to send faster, when using the SMTP option. You can choose to skip the logging of emails to your “Sent Mail” folder which more than doubles the sending speed.
Just how fast is fast?
There are too many factors to give you average speeds, because the speed at which a 5 KiloByte email sends over SMTP is far greater than the speed at which a 5 MegaByte (MB) email sends over SMTP. Rest assured, though, if you’ve been annoyed at how slow GMass sends over SMTP, you’ll be thrilled with this new option. Just check the “Fast sending” option when selecting to send via SMTP.
Here’s a screenshot:
Consequences of fast SMTP sending
Because sending fast skips logging emails in the “Sent Mail” folder, you can’t use reply-based auto follow-ups when this option is on. You can still use open and click based auto follow-ups, but your auto follow-ups can’t be based on whether the recipient replies. This is because the primary way GMass detects whether a recipient has replied is by examining the “thread” of an email. Without the original sent email in your “Sent Mail” folder, replies can’t be “threaded”.
