An email verification API can be useful for many online businesses including e-commerce sites, bloggers, digital marketers and social influencers. Email verification can help you gain more sign ups and improve the quality of your mailing list by eliminating fake, inactive and disposable email addresses. It can also help you cut down your bounce rates and improve your email delivery rate for valid customers.
How to validate email address using API?
A good email verification API will run multiple checks on each email address. First, it will ping the email server for a response. This is similar to the EHLO message that SMTP servers send to one another when they start an email session. Once the verifier receives a server-reply it will know that the email is valid and active.
This is one of the most important steps in the process. Invalid and stale emails can cause your email deliverability rates to suffer, which in turn will impact the effectiveness of your marketing campaigns. A good email verification service will remove such emails from your mailing list before you use it for your next campaign.
Some email verification services also perform syntax and grammar checks on the email address. This helps to eliminate common mistakes such as missing a ‘@’ symbol or incorrectly spelling words. This can save you a lot of time and effort and make your mailing lists more accurate and trustworthy. It will also keep your email delivery rates high and improve the overall performance of your email marketing campaigns.
