Use SimpleSend from Claude
Ask Claude to draft a lead list, research a company, send a campaign as an email sequence from your own mailboxes or export it, or run a LinkedIn campaign from your connected account. Claude writes the emails on your Claude plan; SimpleSend supplies the lists, the company research, the verification, the export, the email sending and the LinkedIn sending.

Add SimpleSend in Claude's connector settings, or paste a personal key into Claude Code.
- 02Brief
Tell Claude which list, what you sell, who to, the ask, and what to research.
- 03Draft
Claude writes each sequence from SimpleSend's company dossier and person card, and saves it for you to review.
- 04Send
Claude builds a sequence, runs pre-flight and launches from your warmed mailboxes on your go-ahead, or you export.
Setup
claude.ai and Claude Desktop

LinkedIn from Claude
With a LinkedIn account connected in SimpleSend, Claude can build and run LinkedIn campaigns the same way the dashboard does: a connection-request note, follow-up messages after the invite is accepted, light touches while it is pending, and pacing (daily invite cap, quiet hours, days between messages). Claude shows you the preview and asks before anything is sent; you can pause, resume or stop from Claude or from the dashboard. Sends spend LinkedIn actions (9,000 a month per seat, included with the add-on), never credits.

| get_linkedin_account | Whether a LinkedIn account is connected, what it did in the last 24 hours, the default pacing and limits | Free |

| reply_linkedin_thread | Answer in a conversation from your LinkedIn account, after you approve the text; ends that person's campaign sequence | 5 LinkedIn actions |
Email sequences from your own mailboxes
Email sending is included on Pro and Teams; on Individual it's the Email Sending add-on ($49.99/mo). With it, Claude can write a sequence or build one from a drafted campaign, enroll a list, pick the mailboxes you bought and warmed through SimpleSend, send you a test, run pre-flight and launch, showing you the summary first and launching only on your go-ahead. Every email carries your signature, an opt-out line, an unsubscribe link and your business mailing address; a reply stops that person’s follow-ups and lands in the Sequences inbox in the web app. Buying domains and mailboxes stays in the web app.
| Tool | What it does | Cost |
|---|---|---|
| get_sending_status | Whether sending is available, which mailboxes are ready or warming, whether the mailing address is set, and the web-app links for the rest | Free |
| list_sequences · get_sequence · get_sequence_leads | Your sequences with their state, steps, settings, merge tags and leads | Free |
| create_sequence | A new sequence, empty, from a drafted campaign (its contacts keep their drafted wording) or from a lead list | Free |
| save_sequence_steps | The steps: subject, body as text with merge tags, delay; validation problems come back instead of failing | Free |
| enroll_sequence_leads | Add a lead list, a drafted campaign or rows (with custom columns as merge tags); up to 5,000 rows a day | Free |
| update_sequence_settings | The mailboxes it sends from, the schedule, tracking and stop rules | Free |
| preflight_sequence · preview_sequence_step | What a launch would check (ready and held leads and why) and one step rendered for one lead | Free |
| send_sequence_test | Step 1 to your own account address from one of your mailboxes; never to anyone else | Free (3 per 5 minutes) |
| launch_sequence | Two steps: the pre-flight summary with a confirmation token, then the launch, only after you say so; up to 10 launches a day | Free; needs sending on your plan (included on Pro and Teams, an add-on on Individual) and ready mailboxes |
| control_sequence | Pause, resume or stop a sequence | Free |
What else the connector can point you to
Ask Claude “what else can SimpleSend do?” and it calls discover_features: every feature below with its status on your account (available, needs an add-on with the price and link, not connected with the setup link, or web-app only) and a guide it can read for the setup steps, written from these docs rather than from memory. When one fits what you are doing (a brief that mentions calls, a list without emails, a LinkedIn campaign without a seat, an export you could send from SimpleSend instead), Claude may add one short tip to a reply, at most once a week per topic and never when something is being sent. Turn tips off in Profile → Claude.
- Email sequences
Send from warmed mailboxes on domains registered in your name, with schedules, daily caps, pre-flight checks and unsubscribes handled; a reply stops that person's follow-ups. Claude can build, test and launch one on your go-ahead. Suggested when you want the emails sent rather than exported.
Pro and Teams · Email Sending add-on on Individual, $49.99/mo
- Sequences inbox
Every reply across your mailboxes in one inbox, labelled by intent, with AI reply drafts and reply alerts; a request to stop is suppressed across your team. Claude sees who replied; reading and answering happen in the web app.
Web app · Sequences
- Talk Tracks + Chrome extension
A cold-call card per contact, shown inside HubSpot, Salesforce, Zoho CRM, HighLevel and parallel dialers the moment a record opens. Claude suggests it when your brief mentions calls, dialing or objections.
Web app · Chrome Web Store
- Find Leads
Search B2B contacts and enrich a list with verified emails and phone numbers. Suggested when a list lacks emails or phones.
Included with every paid plan · paid in credits
- LinkedIn outreach
Connection notes, follow-ups and InMails from your own LinkedIn account, paced by SimpleSend. If your plan lacks it, Claude tells you the price and where to add it.
Add-on · $80/mo on either plan
- HubSpot list import
Read-only OAuth; any HubSpot list lands in the draft wizard, deduped across your team.
Web app · Profile
- Saved briefs
A brief, sequence and research targets stored once and reused — from the web app or from Claude.
Web app · Claude
- Research targets
Up to five per campaign: 5 credits per target per company, cached 30 days. Suggested when a campaign is created without any.
Claude · create_campaign
- Custom CSV columns
A research target can read a column of your CSV instead of the web, so notes you already have land in the emails.

Data and privacy
- Claude sends SimpleSend only the arguments of the tools it calls; SimpleSend returns your own lists, campaigns, drafts and research, your sequences and mailbox status, and your LinkedIn campaigns and inbox conversations.
- Every tool call is logged for 90 days: tool name, time, outcome, credits and your IP address. The arguments themselves are never stored.
- Company research reads public web pages; it never stores your prompts or conversation.
- Personal keys are stored as one-way hashes and shown once. Revoke a key or a connection at any time from Profile.
- See the privacy policy for the full picture, including what reaches Anthropic and our search provider.
- Reviewing this for an organization? Security and administration covers authentication, isolation, limits and what an administrator can control.
Questions
- Can Claude send email for me?
- Yes, from mailboxes you bought and warmed through SimpleSend. Sending is included on Pro and Teams; on Individual it's the Email Sending add-on ($49.99/mo). Domains are registered in your name and set up in the web app, never from Claude. Claude writes the steps, enrolls a list, picks the mailboxes and runs pre-flight; it shows you the summary (who is ready, who is held and why, the finish estimate) and launches only when you tell it to. Every email carries your mailbox signature, an opt-out line, an unsubscribe link and your business mailing address, and a reply stops that person's follow-ups. If you connected Claude before this was possible, Profile → Claude asks you to approve the updated capability list once.
- Do I need a SimpleSend account?
- Yes. Connecting from Claude signs you in to SimpleSend (or lets you start the 14-day free trial), and everything Claude creates (lists, campaigns, drafts, sequences) lives in your account, where you can review it, export it or send it.
- What does it cost?
- One rule: drafting in Claude uses your Claude plan and charges no SimpleSend draft credits. Research through SimpleSend costs 5 credits per research target per company, once per 30 days. If Claude researches with its own web search instead, SimpleSend charges nothing. Sending email and LinkedIn actions use no credits. Plans start at $50/mo: Individual is $50/mo with 4,000 credits; Pro is $250/mo with 14,000 credits and email sending included (1 domain and 3 mailboxes); Teams is $275 per seat / mo, 3 seats minimum, with sending on every seat. On Individual, email sending is the Email Sending add-on ($49.99/mo); LinkedIn Outreach is $80/mo on either plan. The 14-day free trial comes with 375 credits and no card.
- Which Claude plans work?
- Every Claude plan, including Free. SimpleSend is in Claude's connector directory: open its listing and click Connect, or in claude.ai or Claude Desktop go to Customize → Connectors, click + and search for SimpleSend. On Team and Enterprise, an Owner adds it first under Organization settings → Connectors → Browse connectors, then members click Connect. Claude Code works with any plan that runs Claude Code, using a personal key.
- Can Claude send LinkedIn messages for me?
- Yes, through the LinkedIn account you connected in SimpleSend, with the LinkedIn Outreach add-on (if your plan lacks it, Claude tells you the price and where to add it). Claude builds the campaign and shows you the connection note, the messages and the pacing; nothing goes out until you tell it to launch. Sends run at the daily cap and outside quiet hours, exactly as from the dashboard, and use LinkedIn actions (9,000 a month per seat, included with the add-on) rather than credits. Claude can also read the replies in your LinkedIn inbox and answer one once you approve the text. Connecting the account itself stays in the web app, because it needs your LinkedIn password and verification code, which go to our LinkedIn automation partner (listed in our privacy policy), never to Claude.
- What can Claude see?
- Only what you can see in your own account: your lists, campaigns, drafts, sequences and mailbox status, LinkedIn campaigns and LinkedIn inbox conversations. Nothing from other accounts, and never your billing or connected-app credentials. Revoke a connection or key any time from Profile.
