Checking for valid email addresses is the key to generating accurate data. In the world of email marketing, the general rule is that 97% of all lists should contain valid addresses.
If there are 3% of contacts with errors, the sender’s IP is blocked and they are classified as a spammer.
Therefore, email verification brings the direct benefit of list validation, and this is essential for professionals who work with mass mailings.
But do you know how to check for valid email correctly? Keep reading to find out more about this practice, which is so important to the success of a campaign.

How to check for valid email
The email query can be done through marketing automation or manually. Basically, there are 3 ways to check for valid email:
- Using the free email verifier: this method works best for small contact lists, as the data is entered manually. The verifier analyzes address by address and validates the data automatically. This way, you build a list free of bounces.
- Uploading lists: bulk email verification is essential for large email bases. Through it, professionals have a tool that helps message deliverability and, consequently, campaign ROI.
- Installing a real-time verification API: websites, landing pages, applications and other web services that collect data are susceptible to emails with errors. The verification API will check emails and prevent suspicious addresses from entering the database. This guarantees the protection of registration forms and the construction of a clean email database.

What happens if I don’t make the appointment?
A list without an email query ends up damaging communication and sales, since the sender’s IP address can be taxed as a spammer.
This is because ISPs’ anti-spam filters are real hunters of suspicious emails.
A list without the practice of checking for valid email can become a repository of rejected emails. And moving from this stage to blocking is only a matter of time.

Types of bounces that can be part of an unverified list:
Invalid emails are those that have undergone changes that make them unsuitable for use. These are typos, which can be in the domain or in the user name. The first case can still be corrected, and the email can be made fit for use again. But if the error is in the username, only an email verification service will be able to identify the mistake and remove it from the list.
Temporary or disposable emails are active for a short period of time. Once they have been used, spammers’ techniques for creating fake email lists collect them. As they don’t engage, these emails will become part of the 3% of bounces that lead to a list being blocked.
Roughly speaking, corporate emails also fall into the category of temporary emails, because they quickly become outdated. This is due to turnover (the flow of employees in and out of a company).
Spamtraps are emails created by ISPs and companies that sell anti-spam services to identify fictitious mailing lists. Emails that have not engaged for a long time can also be traps.
Spamtraps are also often used to identify companies that do not perform email queries. In this way, ISPs view IPs suspected of sending spam.
How checking for valid email helps professionals
The email query identifies the sender’s ID, tracking their online behavior. This guarantees the construction of a sanitized list free of bounces.
What’s more, a healthy email base is the gateway to a successful campaign and ever-improving results, in terms of deliverability, open rates and click-through rates.
In other words, checking for valid email is very important for professionals who use email as a communication channel. After all, messages need to reach the recipient’s inbox, right?
Conclusion
Checking for valid email is inherent to the success of a campaign, and certainly, accurate and reliable email verification should be part of the strategies of professionals who plan ever better results.
