A high bounce rate can be detrimental to your continued email campaigns. In order to protect their customers from unsolicited or unwanted email communication, many Internet Service Providers and Spam Filters look at previous bounce rates for your sending email address to determine whether to deliver your emails. The logic is this: if an email has a high bounce rate (20% or greater), the sender is a potential spammer, “making up” email addresses to try to hit a lot of recipients with their message.

If a lot of your emails are bouncing, we do recommend removing those particular email addresses.

Online Outbox utilizes a technology called “Automated Bounce Processing”, which helps control your bounce rate. If a particular email address bounces three times within a relatively short period of time, that email address is automatically deactivated from the Contact List. This helps keep your emails deliverable over the lifetime of your email campaign.
