Frequently asked questions

Everything you need to know about email verification

Answers to the most common questions about how FeedLead validates emails, cleans lists in bulk, and integrates with your existing tools.

What is email verification and why does it matter?

Email verification checks whether an email address is valid, deliverable, and safe to send to. It flags syntax errors, disposable domains, and inactive mailboxes before you send a campaign, so you avoid bounces and protect your sender reputation.

How does FeedLead verify email addresses?

FeedLead runs each address through multiple checks — syntax validation, MX record lookup, a live SMTP handshake, disposable domain detection, and gibberish filtering — to determine whether it is deliverable, risky, or invalid.

Can I verify a large list of emails at once?

Yes. Upload a CSV file and FeedLead verifies every address in bulk, so you can clean a list of any size in minutes instead of checking addresses one by one. Results can be exported as CSV on every plan.

Does FeedLead offer an API for email verification?

Yes. The FeedLead API lets you validate email addresses in real time as they are entered — in signup forms, CRMs, or backend systems.

Will using FeedLead reduce my email bounce rate?

Removing invalid, disposable, and risky addresses before you send reduces hard bounces and helps keep your sender reputation and inbox placement healthy.

Do unused credits roll over?

Yes. When your paid subscription renews, unused credits roll over to the next billing period, up to 50% of your plan's monthly credits. Rolled-over credits are valid for one billing period. Credits from one-time packs are different: they never expire.

Which plans include the deliverability score?

The deliverability score is available on the Growth and Business plans. Scores are billed from a separate credit pool, so they never use up your email verification credits.

Is there a free plan?

Yes. You can get started on FeedLead's Free Plan with no credit card required, and upgrade as your verification and lead generation needs grow.
