Email verification for appointment setting agencies
Appointment setting agencies are paid for meetings booked, and every bounced email or dead lead is time a setter did not spend on a real prospect. Verify each client's list before it reaches the setters, send the confirmed addresses, and move the unconfirmed ones to a phone-first track. Agency ($249 a month) keeps each client's lists in its own workspace and gives 15 seats to your team.
Plan details as of 23 Oct 2026. The pricing page is the source of truth.
The use case
You run outbound for several clients at once: a list per client, emails from shared or client-owned domains, and setters who follow up by phone. Verification sorts the list before the first touch: valid addresses go into the email sequence, risky ones (catch-alls, role inboxes) are better worked by phone, and invalid ones are removed so they never count against the client's sending domain.
The workflow
- 1
Workspace per client
On Agency, create a workspace for each client and file every list under it. History and exports filter by client.
- 2
Verify before the first touch
Upload the list and verify. Each row gets valid, risky or invalid with a reason.
- 3
Email the valid file
Load valid addresses into the sequence. Use the Instantly or Smartlead integration (a lemlist connector is in beta), or export the valid file and import it yourself.
- 4
Phone-first for risky
Give risky rows to setters as call tasks. Pro and above include phone format checks (E.164, country, number type from the numbering plan); that is a format check, not a check that the line is in service.
- 5
Share seats with setters
Add setters and account managers as seats (15 on Agency, owner included) so they share lists and results without sharing a login.
Which plan fits
Agency ($249) when you set appointments for several clients and need their lists apart: 750,000 emails a month at full speed, 15 seats and client workspaces. Business ($99) suits a small team working one or two clients, with 5 seats and 300,000 emails a month.
Full speed is a monthly volume, not a promise of hours. Mailbox checks are paced and the day's check capacity is shared between customers, so a very large list takes days. It queues rather than failing, and the job card shows an estimated finish time. Plan client deadlines around that.
Calling and texting carry their own rules (for example TCPA in the US), and verification does not provide consent for email either. Check the rules for each client's market.

Common questions
- Will verification tell us who will take a meeting?
- No. It checks whether an address can receive mail. Whether the person replies depends on the list, the offer and the follow-up.
- Does it check whether a phone number is in service?
- Not on the base plans. Phone format checks read the numbering plan. Live carrier lookups are a separate add-on and report the carrier's line type, not whether someone will answer.
- How do seats and client workspaces work?
- A seat is one person, the owner included: Business has 5 seats and Agency has 15. Teammates share the account's lists, monthly volume and API keys. Client workspaces are on Agency: you pick a client when you upload a list, then filter History and exports by client. Deleting a workspace keeps its lists; they just lose the label.
- What does the priority lane do, and how fast is it?
- Big lists on Business and Agency go ahead of other big lists in the shared queue, within the plan's monthly full-speed volume. Small lists under 2,000 rows always run first on every plan. Full speed is a monthly volume, not a promise of hours. Mailbox checks are paced and the day's check capacity is shared between customers, so a very large list takes days. It queues rather than failing, and the job card shows an estimated finish time. Plan client deadlines around that.
