Good email deliverability

Apart from checking against the millions of email addresses we have in our database, we also use fraud detection services to verify each email address that’s about to be imported.

This process helps with identifying and removing spam traps, invalid email addresses, and frequent complainers (those that have a history of repeatedly reporting email messages as spam).

In addition to verifying every new email address, we have a strict human compliance process before we finally let new users import their contacts.

After they pass the fraud detection step, a teammate will go into the new account to manually review their site content.

Making sure the quality of the site is good; asking them to verify that they are the rightful owner of the site, etc.

It’s not uncommon for us to decline new users’ imports because they did not meet the quality we’re looking for.

Finally, after they’ve passed the steps above, we throttle the FIRST email sent to these NEWLY imported contacts.

So, for example, if a new user wants to send their first email to their 30k contacts… instead of sending all at once, we split them into multiple batches — each batch containing a few thousand recipients.

Again, this throttling is only applied to the first email sent to newly imported contacts. Subsequent emails to these contacts will not be throttled.

This is done as a precautionary measure to further ensure the new user’s email list is healthy.

Every legit email marketing tool throttles your first email send — it’s just a matter of disclosing this info to you or not.

Unlike some email service providers that outsource deliverability to an external company, we manage our email sending and deliverability in-house.

Since there are no “middleman”, we can tackle the root cause of the problem faster — instead of multiple back and forth communication with an external company.
