Supporting a system where people can mass-send emails = enabling spam.
How absurd will you extend this argument? "Oh, yeah, 99% of my customers are spammers, but I'm not the one making them click send! They could've just paid, twiddled their thumbs and not do anything with my product!"
Maybe that's a convenient reason not to check.
In what instances is high volume not spam when using this service? Given one legitimate use case where a customer isn't better off using a cheap MailChimp account.
We never had to bother avoiding any of the measures you deliberately subvert, because our mail was all legitimate.
Granted, doing a 'mail run' with that volume took about a week, but whatever.
If your (client's) recipients aren't all double-opt in, then what you're running could very easily be seen as irresponsible (and that's me being polite), no matter how much money it's making.
And the phrase "It's not that we're looking the other way... we don't have to look at all" simply means he's delegating spam detection to the Gmail/SendGrid platforms instead.
Yes, and your product helps spammers bypass those detection systems. You even explain it in the post I linked:
> GMass will automatically send 500 emails/day or 2,000 emails/day if your email campaign has more than 500 or 2,000 recipients, respectively. You can also control, however, how many go out per day with the new Spread out setting under the GMass Settings arrow. If left blank, GMass will use 500 (regular Gmail) or 2,000 (G Suite) automatically, but you can override this by setting your own value.
And...
> It's not that we're looking the other way... we don't have to look at all.
That is what the phrase means.
