One of the main problems that any email marketer will have had to deal with at some point has to do with the consequences of sending an email to a database with a high number of incorrect addresses. The main consequence of sending to these addresses is a high bounce rate, which directly affects the reputation of the sender and can mean, depending on the sending platform, that the sending is stopped.
As a reference, the lower the bounce rate, the better, and it should never approach 2%, the threshold from which we can have serious reputation problems.
If we detect that the bounce rate of our campaigns is excessively high, we can resort to email validation solutions. These are tools that check the validity of the emails in our database. Once the database has been passed through these solutions, we will obtain three files, one with the valid thailand business email list emails (the address represents a real email and there is a real address in that domain), another with the invalid emails (that address is not real or there is no real address in that email) and a third with the emails on which the valid/invalid verification could not be carried out.
We recommend, if the problems we are experiencing are significant, to include the dubious addresses in the group of invalid emails to minimize risks.
Depending on the size of the database, the validation process may take more or less time. As a reference, the last time we validated a file of 60,000 records it took around 12 hours to return the results. The main classifications of invalid emails that these solutions return after analyzing our database are:
Incorrect format: for example
No replies :
Bounces : hard bounces due to the email not existing
Bad MX/Domain – The domain is invalid and does not resolve correctly
Spam-traps : These are trap emails published by email service providers such as Hotmail, Yahoo or Gmail on websites such as forums and blogs with the aim of detecting spammers who collect them to send unsolicited emails.
