Hi there 👋🏻,
✅ Email Verification is super important to ensure high email deliverability.
We'll be understanding what it is and how it works.
🤨 What is email verification?
Email verification is the process of confirming that an email address is both valid and capable of receiving messages. Its primary purpose is to ensure that the email address:
Is Linked to a Functional Mail Server: Beyond syntax, verification often includes confirming that the domain listed in the email has a working mail server (known as an MX record) that can accept messages. If the domain or mail server does not exist or is unable to accept incoming mail, the address is considered invalid.
Has an Active Mailbox: Even if the domain and mail server exist, some email addresses may no longer be active, suspended, or closed. Our verification method communicate with the mail server to ensure the specific mailbox is still active and can receive messages. This step is usually performed without sending an actual email to the address, often through a “ping” to the server, though the level of verification can vary by provider.
😮 Why Email Verification Matters for Email Deliverability?
Reducing Bounce Rates: Sending emails to invalid addresses results in “bounces.” A high bounce rate can harm your sender reputation, which can influence how future emails are delivered (e.g., being directed to spam folders).
Improving Deliverability: Ensuring that your leads list is comprised of active, interested recipients increases the likelihood of emails being delivered, opened, and acted upon.
✅ What does SalesBlink check to verify emails?
Syntax Validity: Ensures the email address follows proper formatting standards.
Domain Validity: Verifies that the domain exists and can host email addresses.
MX Record Check: Confirms the presence of valid mail exchange (MX) records for the domain.
Server Response: Pings the mail server to see if it can accept mail for the address.
Mailbox Existence: Tries to validate that the specific user mailbox is active and can receive messages.
Catch-All Check: Determines if the domain’s mail server accepts mail for all addresses (even invalid ones), which can make it harder to validate individual addresses.
Full Inbox Check: Checks if the mailbox is over its storage limit and unable to accept new messages.
