Catch-All emails have advantages and disadvantages. They risk creating rebounds and negatively impact your delivery rate, but can also open the door on significant contacts. That’s why it’s important to understand them before deciding to include them in your emailing campaign.

What is a catch-all address?

There are two kinds of email addresses: Classic / Standard Addresses and Catch-All email Address. Also called ok for all, the catch-all is a email server, so an email account, configured for the purpose of collecting all messages sent to your domain. The Catch-All email is different from the standard address in the sense that the standard can only receive the emails that are addressed to it precisely and will not accept emails whose address includes an error (existing addresses only).

If, for example, your Catch-All address is david@example.com and that the person sends the message by typing the daivd@example.com address (we notice here the failure of typing), it will be blocked and will not arrive on normal messaging since there is an error in the address. On the other hand, the same message will still arrive on the catch-all address, despite the fact that the address is misspelled.

Thus, the catch-all is a tote address to retrieve all messages that are intended for you, but whose typed address is inaccurate, so supposedly non-existent.

What is the catch-all address for?

In concrete terms, it allows the company that puts it in place to be sure to receive all the emails that can be sent to it. Why ? The mistakes in email addresses are common. Imagine that a customer or other sends you an important email, it would be unfortunate to never receive it because of a simple mistake. Indeed, without catch-all, the email sent to a non-existent address will be rejected, including the error message “not delivered” or “unknown user”.

Another advantage of catch-all emails, it allows your business to avoid receiving a more or less large number of unsolicited emails directly. Everything is sent on the catch-all, there is still only to sort.

Create a catch-all address

Let’s take our example above. You must configure “david@example.com” to be your catch-all address. It will therefore be used to recover all the emails sent to the domain name “example.com”, but whose addresses are inaccurate because badly written.

Attention, be aware that many email hosting services no longer accept the creation of a catch-all address because of the large number of abuse on the part of spammers sending emails to randomly generated addresses.

Catch-all with or without Bounce?

There are two ways to configure your Catchall:

  1. Without bounce; The domain is unknown and the catch-all nursing by the people who send emails. They can not know if the address used exists or not, even by performing a validity test, and will not receive a Bounce message in case of error.
  2. With bounce, the catch-all address is not detectable during the sending test phase, but will be at the time of the real shipment. The sender will then receive an email return with an error message.

Should you include catch-all addresses in your emailing campaigns?

There are advantages and disadvantages. Only the actual shipment will eventually let you know if your email bounces or not. In addition, even if it does not bounce, you will not be fully sure that the message has been received by the target person. Anyway, send emails to Catch-All addresses does not constitute a real risk and should not affect your reputation for sender unless you continue to send bounces, or if invalid addresses are too numerous. Your email can also simply arrive at the right person and will not be lost at least.

To put all the odds on your side, check your list before launching the campaign, Make sure that It is healthy, in any case as much as possible. Look at how emails have been collected. If they are, for example, addresses entered by people registered with your communications, the number of invalid emails will be much lower (less rebound) than if they are addresses from purchased or rented lists. This is even more so if you have used the opt-in or the double opt-in.

Also try to know when you got these contacts. An address obtained several years ago to be obsolete than a recently obtained address.

Finally know that CaptainVerify makes it possible to check the addresses of your contacts beforehand.

Instead of eliminating many potentially significant contacts for your campaign, you can start to familiarize yourself with the catch-all, or to tame it, by integrating for example a defined percentage of collector emails in your list of mail. If the results are positive, you can then increase this percentage. The key is to keep your lists clean, always perform tests and beforehand, and to have valid catch-all emails to possibly make the segmentations.
