![]() ![]() Special characters, such as ! # $ % ^ & ’ * + - / = ?.Uppercase and lowercase Latin letters (A-Z, a-z).The local part can be maximum 64 characters long and can include: They are separated by a character and follow the format of For example, if we have an email address of, the “abc” is considered the local part, and the “xyz” is considered the domain. Valid email addresses consist of 2 parts: a local part (i.e., username) and a domain. In fact, they can be checked and modified manually. One of the most popular problems with email addresses is typographical and syntax errors. We’ve attempted to provide simplified solutions to technical difficulties, so let’s see what they are. In this section, we will show you 6 ways to do so. In this case, verification of an email address without sending an actual email is possible. 6 ways to verify an email address without sending an emailĪs we got to know, sending emails to verify email addresses can harm your domain reputation. With better deliverability, you will see a better open and response rate. Not only will you waste your time on bounced emails, but the messages you send to valid addresses won’t be delivered as successfully.īy taking an extra step to verify an email address before hitting the “Send” button, you will improve your deliverability. The more your emails get bounced, the more likely the messages coming from your inbox will be marked as spam. Why should you verify an email address before actually sending?ĭelivering 500 emails to verified email addresses is actually much better than sending 1,000 messages to unverified emails.Ĭhances are, a significant percentage of those 1,000 emails will bounce. In this guide, let’s learn how and why it’s so valuable to do so. ![]() You can actually verify email addresses without sending emails to all of them. However, if your email list includes a few hundred or even a thousand contacts, this is really time and resource-consuming. The idea is simple - if the email hard bounced, the recipient doesn’t exist. The intent of the weak validation is to catch typos and obvious fake addresses to reduce the bounce rate.For years, it has become a common practice among marketers to verify the validity of an email address before hitting the “Send” button. Individual mailboxes are not validated, so bounces are still possible. If an MX record is found, the promise will resolve as true. If the domain doesn't exist or no MX record is found, the promise will reject or resolve as false. To use, just pass the m圎xists function an email address and it will return a promise. The code below uses the dnsPromises API to check if an MX record exists for an arbitrary email address. Therefore, if the DNS module fails to return an MX record, the email address entered by the user is not valid. I learned that Node includes a DNS module that can be used to look up a host and return an MX record, if it exists. ![]() However, to avoid unnecessary bounces I wanted a way to filter out obviously fake addresses that still passed validation using regular expressions. To ensure the user has submitted a working email address, the application sends a verification code to the address entered at sign-up. For the web application I'm working on, having a valid email address for each user is important because the application allows users to contact each other, but retain some privacy, by using double-blind emails. ![]()
