SafetyMails is an email intelligence service

Quality that the market has adopted

 One of the most rigorous tests a service can undergo is that of the market itself: real customers making use of their features and putting their methods and results to the test.

Another reflection of our quality and reliability is that SafetyMails has been listed among the most innovative marketing startups in the country by the MarTechs 2018 League Insights study.

Going Beyond the Basics: Email critic vs. Verification

 The email validation and verification service is often confused with email syntax analysis, known as critics. This confusion gets even bigger when we talk about real-time forms verification.

The crux of this confusion lies in the fact that many forms have, yes, criticisms for the email field. These criticisms seek to avoid common typing mistakes in the field, such as when someone forgets the @ sign. However, criticism is not enough to verify an email address. Would you be able to tell if the [email protected] email exists? For it exists! And the address [email protected]? It does not exist (at least until today)! That is, two email addresses would go through critic, but only one of them would still be subjected to hard bounce.

Email validation and verification is a process that analyzes each email address in all its possible layers, from basic syntax to checking the existence of the address in the provider. In this process, the steps involve multiple tests, such as RFC analysis, MX record registration of domains, checking the databases of recent consultations, among other methods.

RFCs – What Are They?

 The “Request for comments” are documents maintained by the Internet Engineering Task Force (IETF) that serve to detail and standardize all aspects of a given protocol to be adopted.Therefore, there are,  hundreds of RFCs destined to the most diverse activities on the Internet. RFC 3286 specifies, for example, what necessary specifications are required for data flow (or streaming) services, which allows services such as Youtube and Vimeo to work.

There is even an RFC for creating an RFC: it’s RFC 2026!

In case the email it’s no different. Obviously, as one of the oldest digital means for communication, email addresses have undergone several updates. The first RFC for exchanging email messages was RFC 822 of 1982, which standardized the format of an email message.

RFC 822 was replaced by the 2822, which was replaced by the 5322, updated by 5335, 5336, etc …

The following RFCs were making the previous ones obsolete or adding information according to the evolution of the technology:The most current RFC is number 6531, which also addresses internationalized email addresses, where non-existent characters are used in the ASCII (American Standard Code for Information Interchange) table. That is, other alphabets, such as Cyrillic, Greek, Japanese, etc., can be part of an email addresses.


The anatomy of an email address is tested taking into account the main aspects of the most important RFCs of email protocols (such as RFC 5321, RFC 5322, RFC 6531, etc.), obeying the local-part@domain:

identifies the name of the e-mail box, and comes before the @ sign;

  • local-part: identifies the name of the email box, and comes before the @ sign;
  • domain: identifies where the email box is hosted, and comes after the @ sign.

The combination of local-part and domain forms the email address. There are the characters that are accepted and those that are banned, de-characterizing the email address.

Test flow

 Many validation tools are limited to just making an attempt to deliver e-mail to the address you have tested. Others do not deliver, just opening a connection. When the server confirms the process, they disconnect. Providers already understand this behavior and block people who try to adopt this practice. Therefore, making use of pings is not safe.

SafetyMais has a lot smarter processes and therefore delivers far superior results, helping to protect the reputation of domains, IPs, reducing Leads generation costs, and helping to increase conversions and ROI from various companies.

In its processes, SafetyMails works with Layer-based processes, that is, several tests are performed in the same email address until their status is determined. If any of the test layers fails, the e-mail is invalidated.
