We recommend keeping your Bounce rate below 5% per campaign. Keep in mind that this is the general number and it might differ depending on other aspects such as, for example, your prospect base volume or quality of your content.

Reasons why email bounce

Once the email bounced you’ll receive a response from your prospect’s server with the reason why the email couldn’t be delivered. You can review them in the Woodpecker Inbox:

It is worth looking through them from time to time to check for signs suggesting that your emails might be getting blocked because of SPAM content or your reputation as a sender is getting worse.

Bounce reasons

In bounce messages, you can find the response from your prospect’s servers why the email couldn’t be delivered. You should look out for those who will suggest that your email couldn’t be delivered because you’re not recognized as a valid sender – those might indicate problems with your domain or email reputation. Also, for the ones pointing out your content.

The reasons you should watch out for:

Access denied, traffic not accepted from this IP

550 High probability of spam

Message blocked due to spam content in the message.

Domain reputation

The next thing worth checking is your domain reputation to make sure you’re not listed on any blacklists, which might cause your emails to bounce.

You can check your domain reputation using websites like Cisco Talos ». Just enter your domain or IP address and check the results for it.

How to regain a good domain reputation? »

If your domain happens to be listed on one of the lists, you’ll need to contact its owner in order to get delisted or get instructions on what you need to do in order to have them delist you.

Domain age

After creating a new domain it is important to warm it up properly before you can start using it for cold mailing. The warm-up process lets you establish and verify your domain reputation for sending.

Usually, if the warm-up process is skipped or shorten up, there will be bigger chances of a high bounce rate than with the domain that had proper time to be warmed up for email outreach.

How to check your domain age

STEP 1: Open a domain age checker

For example, and paste in your domain name.

If your domain is younger than 3 months, you need to stop your sending through Woodpecker and proceed with the warm-up process, which you can learn all about in our article How to warm-up a domain »

Also, newly created email addresses also need to be warmed up before you can start sending emails using them. This process is similar to warming up your domain but shorter and you can read more about it in our article How to warm up an email account »

After the proper warm-up process, you can resume your cold mailing campaigns and you should notice that your bounce rate will be lower than before.

Q.: When I will notice an improvement in my bounce rate?

It depends on the cause of your issue: in case you need to warm up your domain or regain its reputation you can go back to sending campaigns after a few weeks or even months. However, if you simply need to update your domain settings, you can resume your campaign right after making those changes.
