Yes, and we highly recommend it. SendVerify provides a real-time Email Verification API that you can integrate directly into your signup forms, pop-ups, and application workflows. This allows you to validate email addresses at the point of capture, preventing bad data from ever entering your system.

SendVerify provides one of the highest accuracy rates in the industry, up to 99%. Our comprehensive, multi-layered verification process ensures that we provide the most reliable results possible, so you can be confident that you are removing harmful emails and protecting your sender reputation effectively.

You can either upload your email list as a CSV file for bulk verification or use our real-time API. SendVerify then performs a multi-layered process that includes syntax validation, domain and MX record checks, and direct SMTP handshakes with mail servers to accurately determine if an inbox is real and able to receive mail.

Email lists decay naturally over time. We recommend cleaning your existing lists at least every 3-6 months. For best results and continuous hygiene, you should use our real-time API on all your signup forms to validate new emails as they come in.

Email verification is the process of confirming whether an email address is valid, active, and able to receive emails. It is crucial because sending to invalid addresses increases your bounce rate, which damages your sender reputation, hurts deliverability, and can lead to your emails landing in the spam folder or being blocked entirely.
