Clean your email lists and identify invalid or risky addresses before they reach your sending infrastructure.
Email verification is the process of evaluating an email address before you use it for sending. Instead of relying only on the format of an address, verification can examine the address, domain and available mail-server signals to help determine whether the address is suitable for your workflow.
Validate addresses collected through signup forms, applications and other customer-facing workflows before they become part of your database.
Evaluate addresses before sending important transactional, notification or campaign email.
Use multiple verification signals to identify addresses that may be invalid, disposable, risky or uncertain.
Use verification results to decide whether an address should be accepted, reviewed, excluded or used in your email workflow.
Give your applications and email workflows better visibility into the addresses you collect and send to.
Go beyond basic syntax checks with domain, MX, disposable, SMTP and other available verification signals.
Add verification to application workflows where an email address needs to be evaluated as it is collected.
Process existing email lists in bulk and separate results before using them for campaigns or other sending workflows.
Integrate email verification directly into your forms, registration flows, applications and backend services.
Get results that your application can use to accept, reject or review an email address.
Connect verification with your broader Sendzovo email infrastructure instead of treating list quality as a separate problem.
Identify addresses that should receive additional review before they enter an important sending workflow.
Combine email verification with transactional email, SMTP, API-based sending, templates and delivery workflows.
Sendzovo evaluates an address through multiple stages and combines the available signals into a verification result.
Email verification goes beyond checking whether an address simply looks valid. Sendzovo evaluates multiple signals to help you understand the quality and potential delivery risk of an address.
Check whether an email address follows the expected email address format before performing further checks.
Check whether the domain exists and whether its DNS configuration indicates that it can receive email.
Identify addresses associated with disposable email services so you can decide how your application should handle them.
Evaluate available SMTP-level signals to help determine whether an address appears capable of receiving email.
Verification results give your application and team the information needed to make consistent decisions about email addresses.
The available verification signals indicate that the address appears suitable for sending.
Verification identified a problem that indicates the address should not normally be used for sending.
The address or domain contains signals that may require additional consideration before sending.
Sendzovo could not confidently determine the final status from the available verification signals.
Add email verification directly to your application and validate addresses as part of your existing workflows.
Verify a user's email address during registration before allowing it into your application workflow.
Check addresses immediately before adding them to an important transactional or notification workflow.
Integrate verification directly into your application and use the result to control your own signup, validation or sending workflow.
Add email verification anywhere your application or business collects addresses that may later be used for communication.
Evaluate email addresses during account registration before accepting them into your application.
Check addresses collected through contact forms, landing pages and lead-generation workflows.
Verify existing lists before sending newsletters, announcements and other permission-based campaigns.
Evaluate stored addresses periodically and identify records that may need attention.
Check addresses imported from another platform, database or CSV file before adding them to your sending workflow.
Verify addresses collected by applications before using them for important transactional notifications.
Verification results can help you distinguish between addresses that appear suitable for sending and addresses that require additional attention.
Addresses where the available verification signals indicate that the mailbox appears suitable for sending.
Addresses where verification identifies a problem that indicates they should generally not be used for sending.
Addresses associated with temporary or disposable email services.
Domains that appear to accept email for addresses even when a specific mailbox cannot be confidently confirmed.
Addresses with signals that may require additional consideration before sending.
Addresses where available signals are not sufficient to confidently determine a final result.
Email verification and bulk email work together. Clean your recipient data first, then use your sending infrastructure to deliver campaigns to the addresses you intend to reach.
Use Sendzovo verification alongside transactional email to make email addresses part of a more controlled application workflow.
Your application collects an email address through a signup form, checkout flow or another workflow.
Evaluate the address and determine whether it appears valid, invalid, risky or uncertain.
Use your application's business rules to decide how the verification result should affect the address.
When appropriate, deliver transactional email through the Sendzovo API or SMTP service.
Email verification evaluates an email address using multiple available signals to help determine whether it appears suitable for sending.
Verification can help identify invalid, disposable, risky and uncertain addresses before they enter an important sending workflow.
Yes. Sendzovo can be integrated into application workflows where individual addresses need to be evaluated.
Yes. Bulk verification can be used to evaluate existing email lists before they are used for sending.
No. Verification provides signals about an address and its mail environment, but it cannot guarantee that a message will ultimately be delivered.
Sendzovo can identify addresses associated with disposable email services where supported by its verification data.
Yes. Verification can be incorporated into application workflows before addresses are used for appropriate transactional messages.
Yes. Verifying an existing recipient list before a permission-based campaign can help identify addresses that require attention before sending.
