An active user is someone you've sent an email to in a given month, regardless of volume. So you could send 10,000 emails to 1,000 unique email addresses and you're billed for 1,000 customers.
Any suggestions on how to better describe that?
I'd describe it as an unlimited number of emails that you can send with a limit of 1000 unique email addresses that you can send to.
Thanks for the suggestions, we'll revise this tonight.
$79/mo + sendgrid (or whoever) fees/mo for A/B testing only?
Why would I leave Aweber/Mailchimp?
Perhaps "subscribers" instead of "users"?
That may be confusing because we focus on transactional email, not campaign email (which subscriber would suggest)
Personally would rather have it be based on number of emails. Make more sense. I'll probably give this a try though!
Thanks Frank! The reason we tier on customers is that we sit on top of an esp like Mailgun, which already bill per transaction.
