verify emails with Evaboot
Evaboot is the only company I could find that easily enables users to quickly export Sales Nav leads to Excel. Additionally, the data enrichment aspect is very solid. The exported data also includes LinkedIn profile headlines and summaries which is a HUGE help. I'd much rather scan those in Excel than in Sales Nav. Lastly, JB and team also provide prompt support when needed. Would absolutely recommend.

How the verifier performs
The same numbers the web app is held to, on every list your agent submits.
- 97%
- Deliverability on safe emails
- 7 checks
- On every address
- 1–2 min
- For a hundred addresses
Guaranteed: a 3% maximum bounce rate on the addresses marked safe. Riskier ones can bounce up to 17%.
Syntax, domain, MX record, mailbox, disposable, catch-all, and the hardest ESPs.
A bulk job of under a hundred addresses typically finishes while your agent polls it.
Toolkit
Everything your agent can do with the verifier
Four categories. Any list works, no Evaboot export needed.
Single check
1 capability- Verify one address on the spot and get its deliverability status straight back.
You ask “Is kwame@ledgerline.io safe to send to?”
Bulk jobs
2 capabilities- Submit a whole list in one job, wherever it came from, and let your agent poll it.
- Browse past jobs, newest first, and pull their verdicts back without a new run.
You ask “Verify the 1,200 addresses in my event sheet.”
Seven checks
4 capabilities- Syntax, domain, MX record and mailbox are checked on every address.
- Disposable addresses are flagged, and the hardest ESPs are still verified.
- Catch-all domains are probed for the real mailbox instead of coming back as unknown.
- Every address ends up safe, riskier or invalid, with nothing left undecided.
You ask “Why was this address marked riskier?”
Credits
1 capability- Each verification draws on the same credit balance as the web app. Check it before a big job.
You ask “How many verifications can I still run?”
Workflow
From any list to a list you can send to
Four steps, before a single email leaves your domain.
- Step 01
Paste
Any list of addresses that did not come from Evaboot: a CRM export, an event sheet, or a file a colleague sent you.
verify_email
- Step 02
Verify
Domain, MX record and mailbox are checked, and catch-all domains are probed rather than skipped.
verify_email
- Step 03
Sort
Every address comes back safe, riskier or invalid, so only the safe ones go into the cold sequence.
verify_email
- Step 04
Come back later
Past jobs stay listed. Ask for last month's verdicts and they are fetched as they were, without verifying again.
list_email_verification_jobs
Hand over the list, get the verdicts
Submit every address in one job, wherever the list came from. Your agent polls it and comes back with safe, riskier or invalid for each one, and a count you can act on.
Verify the 287 emails before I send anything.

One address, checked on the spot
No job and nothing to poll. Ask about one contact and the checks run straight away: domain, MX record, mailbox, and a catch-all probe where the domain accepts everything.

Every job stays on file

Same connection
Building the list from scratch instead?
Same server, same connection. The finder verifies what it finds, so the verifier is for the lists you already have.
Sales Navigator MCP
Build the search, export the leads with match flags, and run your lists, saved searches and alerts.

What does the verifier check?
It checks that the domain accepts mail and that the specific mailbox exists, then returns safe, riskier or invalid. Catch-all domains are probed rather than skipped, which is where most verification tools give up and return an unhelpful unknown.
Can I verify a list that did not come from Evaboot?
Yes, and that is what the verifier is for. Pass any addresses you have, from a CRM export, a webinar signup list, a purchased list or a file a colleague sent you. The verifier does not care where they came from, and the same checks run on every one.
What does riskier mean?
The address is plausible but could not be confirmed, usually because the domain accepts all mail or the server refused to answer. Send to these separately from your safe list, or leave them out of a cold sequence entirely.
How many emails can I verify at once?
A bulk job accepts a list of addresses and runs asynchronously, so your agent submits the list and polls for the result. A list of under a hundred addresses typically finishes in one to two minutes.
Do I need to verify emails the finder already found?
Not straight away. The finder verifies every address as it finds it, so a fresh list from the finder is already sorted into safe, riskier and invalid. The verifier earns its place on lists that came from somewhere else, and on a found list that has sat for a quarter, because addresses go stale and a bounce costs sender reputation across every campaign from that domain.
Do I need a Sales Navigator seat?
No. The verifier works on any list of addresses, wherever they came from. A Sales Navigator seat is only needed if you want your agent to build the list as well, which the Sales Navigator MCP covers.
