Email verification for law firms
Most firms send two very different kinds of email from one domain: correspondence with clients on active matters, and business development to referral sources, former clients and prospects. When a newsletter goes to an old, unchecked list, the bounces count against the same domain your case updates come from. Verification keeps those lists clean and catches typos at intake, without sending anything to anyone.

Where bad addresses come from
Intake forms and first consultations
Addresses typed in a hurry, on a phone or by staff from a call, are where typos such as gmial.com or a missing letter creep in. A wrong address at intake can mean a client never sees the engagement letter.
Closed matters
A client whose matter ended three years ago may have left the employer whose address is on file. The record looks fine until the next newsletter bounces.
Referral, seminar and event lists
Business cards, seminar sign-ups and directories age quickly: lawyers, accountants and advisers change firms, and the old firm address stops working.
Lateral hires and firm mergers
Contact lists that arrive with a new partner or a merged firm come from systems you have never seen, often with years of unchecked records.
Where to verify, and what to do with the answer
| Where | How | What to do |
|---|---|---|
| Website contact and intake forms | Real-time API check, or a form connected through Zapier | Ask for another address when the result is invalid or disposable; offer the suggested typo fix for likely typos. |
| Client and contact database before a newsletter | Bulk upload of the export, or a connected email tool | Remove invalid addresses and mark those records for an update at the next contact. Send catch-all addresses as their own small batch. |
| Referral and seminar lists | Bulk upload before the first send | Drop invalid addresses; decide whether role addresses such as info@ belong in personal outreach. |
| Merger, rebrand or office-move announcements | Bulk check of every historical list you plan to email | This is when old data does the most damage: verify the whole list before the announcement goes out. |
Real-time checks use the email verification API; lists go through bulk verification (CSV or Excel, up to 500,000 addresses per file).
What to watch for in the results
Catch-all domains are common among professional firms
Many firms configure their mail server to accept any address. We test for that and label those addresses catch_all, free of charge; treat them as a separate, carefully paced segment instead of deleting real referral contacts.
Role addresses
info@, reception@ and similar shared inboxes are flagged as role. They are fine for firm-to-firm notices and weaker for personal business development.
Personal addresses for individual clients
Individual clients often use Gmail or Outlook.com. These are flagged as free providers, which is normal for consumer practice areas and worth a second look on a corporate client file.
Every result comes with a quality to act on: good (send), risky (catch-all or unknown) or bad (invalid or disposable), plus a 0-100 risk score and the reason behind it. Read how catch-all detection works.
What it costs
Checking a contact database of 10,000 clients, former clients and referral sources needs at most 10,000 credits: $21.67 at pay-as-you-go prices, about $0.002167 per address. Only definite answers (valid, invalid or disposable) use a credit; catch-all, unknown and error results are free, so the same pack often covers more. Credits never expire.

Questions from law firms
Does verification send anything to our clients?
No. The check asks the recipient's mail server whether the mailbox exists and disconnects before any message is sent. Nothing arrives in anyone's inbox.
What do you see when we verify an address?
Only the email address. No message content, matter details or other client data is involved. Our privacy policy explains what we keep and for how long.
How often should a firm verify its lists?
Before every newsletter or announcement to a list that has not been emailed recently, and whenever contacts are imported. For an actively used contact list, a pass every few months is a sensible routine.
Should business development email come from a separate domain?
Many firms send newsletters and marketing from a subdomain so that a poor campaign cannot drag down the reputation of the domain used for case correspondence. Verification and separation work well together.
Does verification meet our notice or service obligations?
No. It tells you whether an address can receive mail; it is not proof that a message was delivered or read, and this page is not legal advice. Use your firm's usual methods for anything with a deadline attached.
