If you’re sending email campaigns, it’s important to protect your sender’s reputation. This can be done by ensuring that the subscribers on your list are valid emails that have been collected through a permission-based sign-up process or purchased from a reputable third party.
What does it mean if you have a large number of invalid emails on your list?
If you have a large number of invalid emails on your list, it means that you are wasting money on sending emails to people who do not exist or who don’t want to receive emails from you. Your email deliverability will suffer as well.
Why to check for invalid emails?
There are many reasons why you should make sure your email list is as valid as possible.
- It’s a simple way to reduce the risk of being blacklisted by ISPs, which can have a seriously negative impact on your delivery rates and overall reputation with other email marketers.
- Suppose you’re sending out marketing or transactional emails (e.g., newsletters). In that case, invalid addresses will prevent you from getting those messages in front of the right people, making it less likely that they’ll take action on them—and that means more money wasted on messages sent for no reason at all!
- Invalid emails also cost companies an enormous amount of money every year: For example, Gmail estimates that one spam message costs $1 million daily!
How to check for invalid emails?
If you want to check the validity of your email list, here are some ways to do so:
- Use a service like MailChimp or Constant Contact. These services use their own servers to deliver emails, so any invalid addresses can be flagged and removed from your list.
- Use a free tool like Mail Tester. This tool checks for valid email addresses by sending out an email with a link that verifies if the address is active or not. If it’s inactive, it will tell you how long the address has been inactive (usually within 24 hours). You can also use this method at home by opening up accounts on multiple browsers and checking if they work in different tabs—if they don’t open at all or take an unusually long time to load then there’s probably something wrong with them!
How to reduce invalid contacts from future campaigns?
You should regularly clean up your email list, especially if you are an active email marketer. This is because some of your contacts might have left your company or changed their job role, therefore rendering them useless in the eyes of marketing campaigns.
In order to do this effectively, you will need to set up a process for ensuring that only valid contacts remain on your database. A simple option would be to use address validation software such as Return Path’s Email Verification Service which uses data from public sources (such as Whitepages) to confirm if a given email address is valid or not.
Another way would be using an automated email verification service such as MailTester Pro where will verify all emails within a specified period of time and report back whether they are valid or invalid based on pre-defined criteria (e.g. has been used before).
