A bounce prevention tool for emails is an effective way to improve email delivery rates and prevent wasting resources on invalid or inactive email addresses. This is important because a high bounce rate can derail the effectiveness of your entire outreach strategy, leading to reduced email deliverability and lower visibility.

An email bounce is a temporary response from a mail server or mailbox provider like Gmail that indicates your message was undeliverable for some reason. A typical email bounce will include a bounce reason code, which is an RFC standard (Internet Message Format) code that indicates the problem. Bounce reasons can range from “recipient email address not found” to “mailbox size limit reached” to “spam policy violation.”

Top Bounce Prevention Tools for Cleaner Email Lists

A hard bounce means the email address is no longer valid and will need to be cleaned from your database. A soft bounce means the email was temporarily undeliverable, and it may be delivered if you resend the email to that contact. We typically allow up to 7 soft bounces for contacts with no prior subscriber activity and up to 15 soft bounces for contacts with previous subscriber activity before converting the contact to a hard bounce and cleaning them from your audience.

Keeping a close eye on your bounce rates will help you monitor your deliverability and take action when you see spikes in your bounce rate. Regularly reviewing your email list and removing inactive or invalid email addresses will also help keep your bounce rates low and ensure the best possible deliverability for your campaigns.
