![]() ![]() That would be against our data processing terms. Verification is the process of establishing the truth, accuracy, or validity of somethingĭo you store all the email addresses you check?.Validation is the action of checking or proving the validity or accuracy of something.Just a few years ago, verification took over in search engines as it's a term that gets used more in Asia, so we use that word equally now.Īccording to the Oxford English Dictionary Since we started it in 2009, email checking was always 'email validation' when it was being described formally. We use either term to make sure we're reaching everyone who is asking the question. What is the difference between email verification and email validation? This question is related to 'How long will it take to check my list?' The answer to that is more complicated as will depend on the number of emails, server load, the unique domains in the list, mail server rules about the speed we can make repeated contact and other variable factors out of our control. (At the time of writing our API is running at a 444 millisecond response time, returning 74 pieces of data about every email address.) We share our API response times publicly. It's a tool to enhance user experience - not slow it down. Checking an email address shouldn't ever impede an interaction. That's why email verification APIs are used in sign-up forms. Checking an email address should take only milliseconds. It depends on the server, the software and the infrastructure that's making everything happen. How long does it take to verify an email address? Email verification shouldn't involve sending real emails. We don't email the address, we only shake hands with the server and perform other checks with other sources. Do you send an actual email - will the person know I am checking their email address? There are details about response codes and results in this free results guide. We keep these roles up to date with new trends and also hold them in multiple languages. and are identified by checking the email against our lists of hundreds of role titles. That's not information we get from the email server, we get that (and other results) from multiple sources that we either own or reliable third party resources that we check in with. For example, we check if an email is associated with spam, if it's on blocklists or whether it is a disposable email address. Other queries not dealt with by SMTP are more complex. A good example of this would be a company mail server that still received mail for people, long after they have left the business. the sever will accept every email, but it's less likely that the emails you send will be opened. Mail servers set up like this are called catch-all servers. So if you sent an email, it would bounce.ĭeep SMTP detailed responses and information about the mail server itself help to determine whether for instance, the mail server is set up to receive ALL incoming mail to a domain, regardless of whether a specific inbox exists. Basic example - the mail server might say an email inbox exists when it doesn't. Some mail servers are also set up badly and they don't follow protocol responses. At a very basic level, the response status tells whether an inbox exists and is able to receive incoming mail. The response received should follow the SMTP rules (Simple Mail Transfer Protocol) and be coded accurately so that we can interpret the code to give results. We 'ping' a mail server to check the status of the inbox associated with an email address. ![]() Once syntax, DNS and MX checks have been made, and we're sure we're dealing with a real email address, mail server communication begins.Įmail verification is a communication between computers - specifically one is a mail server. SMTP and other sources build an email profile - pinging the server ![]() ![]() Mail servers that are badly set up might be open to being hacked and used for fraudulent activity, which is one reason why we check them out. (To check a mail server we check what are called MX Records). This stage also involves analysing the domain status, ( DNS records) to make sure the domain is real and that a mail server exists and is set up correctly. Once we're sure we're dealing with a real email address we can check it in more detail. In an email address there must be a beginning, an and a dot.domain.
