What is validation?
This is an email address check. All validator services work on a similar algorithm. You upload a file with contacts, and then the program:
Checks the syntax of addresses - errors in spelling of domain addresses, missing characters.
Looks for spam traps. These addresses are created specifically to monitor suspicious traffic. If you send emails to spam traps, you can end up on a blacklist.
Duplicates. If emails are repeated, the program will delete them.
Temporary mailboxes - most often people create them for registration on the site to protect the main mail from spam. As a result, you will send letters, but no one will read them.
Addresses that receive many spam complaints. It is possible that your mailing will also be complained about.
Corporate addresses. Their owners often send commercial mailings to spam.
Checks the contact's activity. If the person hasn't opened any emails for a long time, the validator will get rid of the address.
Why is it so important to clean your contact database?
Usually, collecting contacts and preparing palestine business email list letters takes a lot of time. In addition, you need to pay for mailing services and often the price depends on the number of emails sent. If the base is of poor quality, you will face many unpleasant consequences. Mailings may not reach the subscribers' inbox and end up in spam , and the domain reputation may suffer greatly. To avoid such problems, you need to regularly validate your addresses. It's like house cleaning - if you constantly monitor cleanliness, you won't have to clear away the rubble.
Another way to keep your database clean is to make sure all new addresses are high quality. How do you do that?
Use Double-Opt In
The confirmation subscription method will make your life easier. When entering their email, people can easily make a mistake or typo. But if after registration the user has confirmed the address, then everything is fine and you can safely send newsletters to it.
Don't send emails to old contacts
Let's imagine that you have a new project and you decide to send a mass mailing to contacts from your old database. Let's say right away that nothing good will come of this. Most likely, your subscribers have long forgotten about you and, having received an unexpected letter from you, they may send it to spam. You should send emails only to those subscribers who know your brand and trust it.
Which validator services to choose?
Let's say right away that there are quite a lot of them. But our team has understood one important thing over the years of working in email marketing - all special services for contact base validation work with a large margin of error. They cannot guarantee 100% cleanliness of the base after verification. This is important to take into account.
Addresses can be checked in marketing automation platforms. For example, our marketing automation service enKod checks the syntax of addresses and analyzes whether they have hard bounces. If there are problems with delivery, the platform will not add such an address to the mailing list. Usually, the built-in functionality is enough to not worry about the cleanliness of the database. But if you do not have enough platform functions, you can use specialized services. We have compiled a small top of programs that you can trust:
