Frequently asked questions

Everything you need to know about SendX and email marketing

What file formats can I upload for bulk cleaning?

You can easily upload your email lists in common formats like CSV (Comma Separated Values) and TXT (Plain Text).

How long does it take to clean a large list?

Processing time depends on the size of your list, but our platform is optimized for speed. Small to medium lists are often processed in just a few minutes, while very large lists are handled efficiently in a short amount of time.

What do the different result statuses (valid, risky, invalid) mean?

"Valid" emails are safe to send to. "Risky" emails (like catch-all or disposable addresses) may have lower engagement and should be used with caution. "Invalid" emails are non-existent or have errors and should be removed immediately to prevent bounces.

Can I integrate SendVerify with my forms or application?

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.

How accurate is SendVerify?

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.
