Email outreach
Found them. Now start the conversation.
The people you just found become a campaign in minutes: your message with its follow-ups and variants, your own mailboxes or new ones we set up for you, every reply in one inbox. In the app or from your AI. No second tool, no CSV round trip, no bounces from addresses nobody checked.
Every address checked before it is contacted · Your own mailboxes · Replies in one inbox
Who, what, from where, when
A campaign is four decisions. You make them, we do the rest.
Pick the people, write the opener and follow-ups in up to 20 versions each, choose the mailboxes, set the hours. Argorant re-checks every address before it is contacted, spaces the sends like a person would, stops the moment someone replies and can start a subsequence when a reply says 'interested'.

Tell your AI who you want to reach. It sets the campaign up for you.
Describe the customer in Claude, ChatGPT or Codex. The agent finds the people, checks their emails, drafts the sequence, picks your mailboxes and shows you everything before a single email leaves. You approve, it launches, and it reads the replies too.
Ready to launch. Here is what I set up:
- 486 owners with verified work emails, 14 skipped as undeliverable
- Intro and two follow-ups, shown below for your edits
- 12 mailboxes, 40 a day each, weekdays 08:00 to 17:00 London
Say launch and it starts Monday 08:00. Replies land in your inbox.

Connecting Claude to a B2B contact database
A practical walkthrough of agent-driven list building: connect Claude to Argorant over MCP, scope a list with free counts and previews, then reveal and export only what survives scrutiny.

How to build a targeted B2B list by industry and seniority
A field guide to list definition: why industry filters lie, why seniority is a pattern set rather than a dropdown, how to size a list backward from sending capacity, and the preview-first workflow that catches bad filters before you pay for them.
VerificationJune 10, 2026
Why verified-at-export beats verified-at-collection
B2B contact data decays the moment it's collected. Here's why the timing of verification matters more than the method, what a live email check actually proves, and how pay-per-valid pricing changes the buyer's math.
