There is very little that is more frustrating in the email marketing world than dealing with bounces. Not only are they negatively impactful and threatening to your campaigns, but it can be a bit daunting to prevent them in the first time without the right techniques and tools.
But fear not, we are here today to help you and provide more insight on understanding, preventing and dealing with bounces in your email marketing campaigns.
What are bounces, anyway?
Email bounces are emails that cannot be delivered to the intended recipient of the message. These emails, upon failure to deliver, are then returned to the sender accompanied by additional information on the nature of the bounce. Most services provide bounce report errors to their users, so they may diagnose exactly what is preventing the email from being delivered.
There are two types of bounces: soft and hard bounces.
Soft bounces are temporary errors that cause the email not to be delivered.
These types of bounces are often outside of the control of the recipient and can happen for various reasons, such as:
- Service temporarily unavailable
The recipient’s servers could be temporarily disabled or underoging maintenance, these are usually temporary and your message is likely to be delivered at another time.
- Mailbox is full
The recipient’s mailbox is completely full, so there wasn’t any space left for your message to get through - trying again at a later time may result in your email getting through and being delivered.
- Generic processing errors
Random and unexpected errors do happen, trying again later usually works and your message is delivered.
It’s important to note that while every bounce negatively contributes to your sender reputation, soft bounces aren’t particularly punishing because they originate from events that the sender’s control, which heavily mitigates their impact.
With that being said, it is still best to avoid them whenever possible.
If the term “Sender Reputation” sounds alien to you, please make sure to read more about it, we’ve got some useful resources you can check out on the subject. In essence, sender score is a very important factor in email marketing, and bounces directly correlate with your overall reputation and campaign success.
The other type of bounces you can get are hard bounces. These bounces are very impactful in a negative way if you get them, as they directly and heavily affect your sender reputation.
Avoid hard bounces, always!
Hard bounces are permanent failures and more than often relate to motives which are generally within the control of sender, provided they are proactive and thorough in preparing their email marketing campaigns.
Hard bounces have a long list of motives associated with them, some recurrent ones are:
- Address does not exist
This is probably the most common and upsetting hard bounce there is. Essentially, you are trying to email an email address that does not exist, which is impossible to do, so your bounce is guaranteed.
- Email server doesn’t exist
You’re emailing a server that no longer exists, which is slightly different from an address not existing, but still constitutes a critical failure and results in your message not being delivered to your recipient.
- Content issues
Something in the content of your email is triggering security and spam filters. It’s very important to know what this could be, identify it and remove it or adjust it according to best practices.
It is paramount to avoid hard bounces, not only in the sense of improving the metrics of your campaigns - since less bounces equals to better return on investment - but also to actually protect your ability to execute these campaigns.
Most email service providers or customer relationship management tools and solutions have strict policies about hard bounces, and it does not take an extraordinary amount of them to cause issues in a user account, including temporary deactivation or permanent removal from the platform.
Even if you own your own servers and do all emailing yourself with an inhouse built system, a hard bounce is still impactful on your email marketing, as spam-filters from various domains will start to block your messages because of your low reputation, causing even more bounces. This, then becomes a circular situation - you have more bounces because you have lowered reputation, and your reputation keep lowering because you’re getting more bounces.
Don’t let this happen to your email marketing efforts.
How can I prevent bounces?
There are many ways to prevent bounces, thankfuly - most of which are either simple to do or someone else has made it their business to make it simple to do.
The best way to make sure you prevent hard bounces is to email existing email addresses. This is a simple concept, but making sure you’re always emailing an existing email address is not simple at all - let alone when you have tens of thousands or potentially millions of emails to send to, some of which were collected years ago.
One important note, is that there is a natural bounce rate - around 2% - which is fair to say is the industry standard for what a organic bounce rate should be, anything below this and you’re doing great. Anything above… well…
You can easily calculate your bounce rate by diving your bounces by total recipients and multiplying it all by 100%.
Bounce rate = (Bounces / Total recipients) x 100%
The best way to make sure you’re sending emails to the right addresses and avoid bounces is to verify your contact lists with a reliable, accurate and feature-complete email verification tool.
Email verification software goes a long way into preventing all types of bounces, not only can you detect and distinguish valid addresses from invalid ones, you can also get a sense of the overall quality of an email address.
It is important to consider that with so many types of domains, different characteristics and configurations, not everything is so black and white.
Having functional solutions, such as email verification, to help distinguish the good from the bad is an important card to hold as an online marketer, espefcially one who is looking to prevent or reduce bounces from happening.
Preventing and handling bounces doesn’t stop at email verification, however.
You can also take additional steps to prevent hard bounces, to complement email verification.
Here are some examples of such things you could probably do now:
- Add a double opt-in method
You can add a double opt-in method such as email confirmation. Whenever a new user signs up, they must first confirm their email address by taking an action on an email sent to their registered address.
This is easy and essentially cost free to implement, but it will immediately be very helpful in avoiding fake sign-ups.
- Email personalization
Email personalization is known to improve your chances of avoiding the spam folder and it’s important in the sense that it builds better relationships with your customers.
Email personalization can be as simple as adding your customer’s name to the email you’re sending out, but personalization can be so much more than that if you have a good imagination.
It’s important to find what is most valuable to your customers and make it clear that you know what that is, segment them properly and aim the correct campaign to the right audience and all of your customers will quickly join the best customer profile - a happy customer.
- Improve email deliverability
Improving your email deliverability is essential in avoiding the spam folder, bad reputation and consequent bounces from it. There are many ways of improving your deliverability, from authentication protocols to content redesign and adjustments.
Look for tools that can help you analyze and improve your email deliverability by reporting on the content and technical aspects of your emails.
Consistency and frequency can also improve your deliverability, you’re less likely to be stopped by a filter if you’re frequently delivering quality content that is interacted with by your recipients on a consistent basis.
Whatever you decide to do, the most important piece of information you can take away from this article, is that avoiding hard bounces will critically improve the success of your email marketing campaigns.
