The Bounce House of Email Marketing: Hard Versus Soft Bounces

hard and soft bouncesToday, we’re jumping into the world of email “bounces.” We’ll dive into the nitty-gritty of hard and soft bounces, uncover the reasons why emails bounce, and reveal how to improve your bounce rate. Let’s get started!

Decoding the Bounce: What is an Email Bounce?

In the digital world, a “bounce'” isn’t nearly as fun as it sounds. An email bounce occurs when an email you send can’t be delivered to the recipient’s mailbox. An email bounce is essentially an unfulfilled delivery where it gets sent back to you. It’s the email world telling you, “Hey, that’s a no-go, we couldn’t deliver this email!”

The Tale of Two Bounces: Hard vs Soft

While all bounces are a form of failed delivery, not all bounces are created equal. They fall into two primary categories: hard bounces and soft bounces.

Hard bounces are the bad news bears of email. They occur when the email is rejected due to permanent reasons, like a non-existent email address or a closed email account. It’s like trying to mail a letter to a demolished building. There’s simply no way it’s going to get delivered. Where’s it going to go?

Soft bounces, on the other hand, are temporary delivery failures. These can be due to a full mailbox, a temporarily unavailable email server, or an email message that is too large. It’s like trying to deliver mail to a house where the mailbox is already overflowing – you just have to wait for some space to clear up!

The Why Behind the Bounce: Reasons Why Emails Bounce

Now that we understand the difference between a hard and soft bounce, let’s look at some reasons why emails bounce in the first place:

  1. Invalid email addresses: This is a major culprit behind hard bounces. If you’ve got outdated or incorrect email addresses in your list, you’re bound to run into delivery problems.
  2. Full mailbox: If a recipient’s mailbox is overflowing and can’t accept any new messages, you’re facing a classic case of a soft bounce
  3. Domain errors: If the domain of the email address doesn’t exist or is unreachable, your email will be rejected.
  4. Blocked IP or domain: Sometimes, if your IP or domain has been marked as a source of spam, you may experience both hard and soft bounces.
  5. Email size: If your email is larger than the recipient’s server allows, you might experience a soft bounce.

From Bounce to Bound: How to Improve Your Email Bounce Rate

Bounces can significantly impact your email marketing success. So, what can you do to improve your bounce rate? Here are a few tips:

  1. Clean your email list: Regularly update and clean your email list to remove any invalid addresses.
  2. Use confirmed opt-in: This ensures your subscribers genuinely want to receive your emails and have given the correct email address.
  3. Respect size limits: Keep your emails within a reasonable size to avoid soft bounces due to size limitations.
  4. Use a reliable SMTP relay service: A quality SMTP relay service (hey, that’s us!) can significantly reduce your bounce rate by ensuring your emails are correctly formatted and your IP isn’t on any blocklists.
