We recently started using Zoho and hadn’t sent out campaigns in quite some time. With our first campaign, we saw a high number of bounce backs, which we expected due to the age of some contacts in our database.

After doing some research, I understood that Zoho would automatically stop sending emails to bounced contacts. However, after sending our second campaign this week, I received a warning email about a high bounce rate. The confusing part is that there don’t appear to be any hard bounces in the analytics for this campaign, presumably because Zoho is already suppressing those contacts.

So why are we still receiving high bounce rate warnings?

Do we need to export and permanently delete bounced contacts from our database in order to improve our bounce rate, or should Zoho already be handling this automatically?
