Introducing Mailmeteor BounceShield: Say GoodBye To Bounces

- Published: - 8 minutes read

Are you tired of bounces ruining your email campaigns? You’re not alone. Today, we are adding one more feature in Mailmeteor to help you send successful mass email campaigns. Meet Mailmeteor BounceShield.

Sending emails at scale is a challenging task. There are numerous factors to consider. From tidying up your contact list to selecting the appropriate subject line and timing. There are just so many things to keep in mind.

But there’s good news. Today, you’ll say goodbye to bounces once and for all.

What’s the issue with bounces?

First, let me explain what a bounce is. When you send out emails, it’s possible that the recipient’s email address is invalid, which means that the message will be returned to you just like a postcard that gets sent back to the sender by the postman with a message that there is nobody at the address. There are many reasons for that: it could be a small typo, the recipient’s inbox is full, he/she has left the company or other similar reasons.

Bounces are bad for email marketers. They dramatically affect your emailing reputability as you’re sending to a dead end. Also, within Gmail, each bounce decreases your Gmail quota. That’s why we have always recommended senders to clean up their contact lists before sending campaigns.

However, we are aware that this verification process is typically done manually and is quite costly. To address this issue, we formed partnerships with the most effective email verification platforms last year, providing our customers with discounted rates.

Despite this effort, it’s still relatively costly and hard to clean your contacts list. For example, validating all email addresses for a campaign consisting of 10,000 emails would cost around $50 and about 10 minutes of your time.

Free and unlimited email validation

Starting from today, all our Pro and Business customers are automatically protected with Mailmeteor BounceShield. The BounceShield is a fully automated service that verifies email addresses in your campaigns and detects potential bounces before sending any emails.

With the integration of our bounce shield, you can expect a significant reduction in bounces, and save a substantial amount of money that would have otherwise been spent on email verification services.

To put things in perspective, here’s a calculator to estimate how much you can save compared to common email verification tools pricing:

How much will you save?
Mailmeteor BounceShield is included at no extra cost on Pro and Business plans.
Some Examples
Emails per month Save up to
5,000 emails $25
10,000 emails $50
25,000 emails $125
50,000 emails $250

From small to very large senders, Mailmeteor BounceShield will save you a lot while maximizing your deliverability.

And it doesn’t count the time you’ll save, as our BounceShield is automatically checking your email campaigns, without any extra effort on your part.

How does BounceShield work?

About a year ago, we introduced a free email verification tool. Email Checker detects when an email address isn’t valid by checking for typos and technical configurations (such DNS, MX and SMTP records).

It gained tremendous usage and gave us great feedback to understand how to scale an email verification service (like you could use at NeverBounce or Bouncer).

Mailmeteor BounceShield is the logical next step. By integrating our email checker directly into Mailmeteor, we automatically clean your contacts list so you don’t have to. This way you receive less bounces and preserve your email reputation.

When an email is detected as invalid, the email will be marked as failed in the Dashboard:

Our BounceShield verifies your contact list in real time, and works in the background as fast as possible. So you can enjoy seamless and effortless email protection that helps you grow your business, while we take care of the rest.

What’s next?

If you’re on the Pro or Business plan, Mailmeteor BounceShield is already activated on your account, and there is no need for you to manually enable it. If you aren’t on these plans, look at our pricing options.

We’re really excited to release this new feature today. To our knowledge, Mailmeteor is the first email marketing platform to include an unlimited email verification service at no extra cost.

So, we really hope that you’ll enjoy it. As always if you have feedback or want us to implement another feature, feel free to reach out by filling out this form.


What is a bounce shield?

It’s a service that automatically verifies email addresses and detects bounces before sending an email. It’s included at no additional cost in Mailmeteor’s Pro and Business plans.

What does it protect me from?

Mailmeteor BounceShield will protect your email campaigns from bounces. By verifying if you’re sending to a valid email address you make sure your email marketing campaign is more successful while preserving your email reputation.

How many emails does it verify?

Mailmeteor BounceShield verifies all the emails sent through your Mailmeteor account. Whenever it detects an invalid email address, it will flag it in your Dashboard.

There’s no limit to the amount of email addresses it will verify for you. For example, So if you send 10,000 emails per month, Mailmeteor BounceShield will verify all your 10,000 emails against potential issues.

Does it catch all bounces?

Mailmeteor BounceShield works in real-time. So it will catch 99% of soft and hard bounces. However, there may be instances where you still receive a bounce, despite verifying the email address beforehand. This could be due to the email being deleted between the time it was verified and when it was actually sent. Also, in some cases, a bounce can only be detected by actually sending an email to the email address.

Can I turn it off?

Mailmeteor BounceShield is always on and works in the background. If you have use cases where you’d like to turn it off, please let us know by filling out this form.

How much does it cost?

Mailmeteor BounceShield is included at no extra charge in our Pro and Business plans, and all clients who have already subscribed to these plans have now this feature enabled on their accounts.

How to handle bounced emails?

If you are using Mailmeteor BounceShield service, then you don’t need to worry about handling bounced emails yourself as the service takes care of it automatically. BounceShield will verify the email addresses in your campaign and detect potential bounces before any emails are sent.

If there are any emails that BounceShield identifies as potentially bouncing, Mailmeteor will not send them and will mark them as “bounced” in your Mailmeteor account. You can then review the list of bounced emails in your Mailmeteor dashboard, and take appropriate action to handle them.
