Email is the backbone of how we communicate, from transactional messages to marketing campaigns. However, when emails are sent incorrectly and don't get delivered to the inbox of recipients, it can be a costly problem for both sender and recipient. That's why companies like emailvalidation.io exist: we help email marketers and senders deliver their emails reliably by ensuring that the message is properly formatted, has all of the necessary information attached to make it readable by any device or service provider (SPs), and contains no malicious code or links that could compromise user data or privacy.
Emailaddresses are case-sensitive and must contain at least one character. They should not contain spaces or tabs, but may include punctuation marks such as hyphens and periods. An email address cannot be longer than 256 characters.
The format of an email address is:
Domain validation is the process of verifying that an email address is valid. It can be done by sending an email to the address, or by sending a request to the domain name associated with that address. If a message is not received back from either action, it's likely that the email was filtered out as spam or blocked by your ISP.
When we talk about domain validation in terms of email deliverability, we mean checking whether there's actually an active server behind your domain name—and if so, what kind of response you get when trying to send messages through its mail server (if any).
The first step in email deliverability is to verify that your MX records are set up correctly. MX Record Validation is the process of checking that the MX records for a domain are set up correctly, and if they aren’t, emailvalidation.io can help you get them corrected. It’s critical to perform this task before going any further because if your domain does not have correct MX settings, you will experience issues with SPAM filters blocking or filtering out all emails sent from it.
MX Record Validation is performed by sending a test email to an address used by the mail server (i.e., firstname.lastname@example.org). If outgoing mail servers are unable to connect with an external mail server during delivery, then there may be an issue with one or more of your domains' MX records configuration settings; however, when everything goes according to plan during delivery testing then there shouldn't be any problems related to setting up these particular settings correctly within each respective account's control panel area under "Advanced" section where most ISPs allow users access through both POP3/IMAP4 protocols as well as their own proprietary protocols such as SMTP/POP3S/.
SMTP validation is a best practice for email deliverability. SMTP validation involves sending a test email to the receiving mail server and checking that it can accept emails from your domain.
If you don't have an inbound mail server, or if you do but are having trouble with delivery, this is something you should consider setting up.
Disposable Email Address (DEA) detection is a problem that can cause your deliverability rates to take a nosedive. Here's why:
● DEA detection means that the email address is not valid. In other words, it's not really an active address and it doesn’t belong to anyone at all.
● DEA detection also means that the email address is not active because it was only used once before being abandoned or discarded by its owner.
● Free Email Address (FRE) detection will identify email addresses that end in a top-level domain that is not owned by the user. This can occur for a variety of reasons:
● The free account was created with an incorrect email address, so it’s being routed to another account on Gmail or Yahoo.
● The user changed their password and used their old one while activating their new account, which now forwards all messages to this other account.
● A hacker spoofed your domain name and used your company's name to create an email address at Gmail or Yahoo! Again, these are just some examples; there are many ways in which FRE may be generated, but they all share the same goal: making sure you don't get any emails sent to them by mistake!
Catch-all Mailbox Detection is a feature that allows you to detect whether or not an email address is a catch-all mailbox. This can be helpful when looking for valid contact information for your contacts.
To use this feature, you will need to have already uploaded the list of emails you would like to check in the “Email Validation” tab. Then, select “Catch-all Detection” from the dropdown menu under “Advanced Options” and click “Continue”:
Once you have selected your desired options, click “Start Test” to begin testing:
