When you upload a list for email verification on SafetyMails, you need to wait for some time until the report become available to you. This time is valuable and essential because our algorithms are dedicated to verifying all your emails with the utmost precision.

If you want direct access to an explanation of a specific part of your email verification report, use the index below:


SafetyScore is the quality score of an email list imported into the tool, based on the criteria adopted by SafetyMails.

This score primarily takes into account the incidence of invalid emails and spam traps, responsible for most blocks and drops in reputation in email marketing.

The higher the stars, the better the quality of the list imported into SafetyMails.

This score can be seen by hovering over the stars below the name of your database.

Email Statuses

After email verification, addresses are classified according to Safetymails’ criteria.

The distribution of these emails can be seen in a graph and also in a table, like this:

The table below explains the statuses presented:

GREEN zone

These email addresses can be used in your campaigns.

Validemail address whose existence has been confirmed.


These email addresses can harm your campaigns due to their low deliverability.

LimitedValid Email Addresses that Knowingly Have Limitations on Receiving Capacity, Such as Intermittent Server Issues. This Can Lead to Delivery Problems.
ScrapedISPs admit that these emails have been created by automatic generators of addresses such as “contact, adm, sales, etc” for various domains, characterizing spam by “Dictionary Harvest Attack”. They can also be emails from callcenters or others that do not have a responsible individual.

RED zone

These email addresses MUST NOT be used in your campaigns.

InvalidE-mail classified as non-existent or deactivated in a domain. Hard bounce.
SpamTrapsTrap emails are used to capture spammers, causing immense damage to the reputation of IPs, leading to blocks and a decline in deliverability. They are not disclosed in the database to contribute to the fight against spam.
Invalid DomainDomain does not exist or has several flaws.
Syntax ErrorE-mail that does not comply with the syntax rules set by email providers and market RFCs, since it invalidates the email.


These email addresses have characteristics that make sending them UNRECOMMENDED. Therefore, it is up to the client to decide what to do, but they will be subject to problems with email providers.

DisposableE-mails from temporary address services. They are valid, but only for some time (hours or minutes). After this period they become invalid and impair deliverability.
JunkE-mail addresses that have negative elements that will be identified by ISPs and sent to the junk folder or spam. E-mails with repeated characters, swear words, numeric sequences, etc.
UncertainKnown as “Accept All” and “Deny All”. That is, they receive all messages or deny all messages, regardless of their content. The result cannot be confirmed.

GRAY zone

These are e-mails for which we have no information and therefore no credits have been debited from the customer’s account. There is no validation response.

PendingEmails for Which We Currently Lack Information in Our Database. After a New, Specific Analysis Period for These Addresses, We May Still Lack All the Information. Credits for These Emails Are Refunded to Your Account.
