Cold email, run with your AI.
Connect Senders.ai to your Claude or ChatGPT and you run your outbound together — strategy, copy, target lists, full email sequences — using everything it already knows about you and your business. Most of it happens right inside your chat, and nothing sends until you say so.
“I wanted a way to use all the context and power my Claude already has to run outbound end to end — and Senders.ai makes that happen.”
Get real value before you pay.
Ask your Claude or ChatGPT about Senders.ai and it plans your outbound with you — no account. Connect a free account and it checks your domain and analyzes your copy too. You only pay when you’re ready to find prospects and send.
Plan it out first — no account needed.
Before you connect anything, ask whether Senders.ai fits your outbound. It reads our docs and strategy guide and plans with you — define your ICP, build target profiles, draft copy, design a sequence. Real output you keep. No endpoint, no account.
Connect, and build what you planned.
Add mcp.senders.ai/mcp to your Claude or ChatGPT and a free account turns your plan into real work — build and store your campaigns, prospect lists, and suppression, then check your domain’s deliverability setup and analyze your drafts for spam risk, all in the chat. Finding live prospects and sending start on a paid plan.
In Claude or ChatGPT, add the connector below. A free account unlocks domain health checks, spam-and-copy analysis, and campaign, prospect-list, and do-not-contact building — all from the chat.

Free to plan. Pay when you send.
The strategy is the product.
Every plan — free included — comes with the Senders.ai playbook your AI reads and applies: who to target and why, sequences that don’t nag, copy that earns replies, and a deliverability-first method. It’s the part most tools leave out.
Start by exploring with your AI — no account needed. When you’re ready to send, pick a tier:
- Free account, no card
- Build campaigns + plan your ICP
- Store prospects + suppression (DNC) list
- No sending, research, or data tools yet
- One mailbox — Gmail or Outlook (your own)
- 25 sends/day, with an automatic warmup ramp
- Research, verify + analyze via MCP
- 1,000 research requests/mo
- Up to 5 mailboxes (250 sends/day total — 50 each)
- Shared suppression list + shared credits
- Connect your own Apollo account
- 10,000 research requests/mo + concierge onboarding
- Managed SMTP — 200 sends/day base
- Domain + Google Postmaster monitoring
- Inbox placement testing
- Volume scales with add-on senders →
Extra Single mailboxes are +$25/mo each (a 3rd nudges you to Team). Premium Warming is +$20/mo per mailbox on Single and Team — included on Business.
Research requests are included monthly (1,000 on Single, 10,000 on Team and Business; +$10 per extra 5,000). Verified-email / data credits are $0.05 each on any paid plan, with an optional contact-data module at +$10/mo for 200 credits.
Your AI can walk you straight to a free account. Paid plans take a quick human checkout — we don’t let an AI spend your money.
The Business plan scales with your volume.
The Business plan starts at one managed sender doing 200 emails a day. Scale the way that fits: bring more of the mailboxes your team already uses, or grow managed SMTP volume in clear tiers. Either way, every sender warms and ramps so deliverability holds as you grow.
Add the inboxes you already send from
Connect more Gmail or Outlook mailboxes. Each one ramps and respects its own daily cap, so every sender stays healthy as you add people and volume.
- Single: 25 sends/day per mailbox · Team: 50/day per mailbox
- Single: +$25/mo per mailbox (the 3rd moves you to Team)
- Team: 5 mailboxes — 250/day total
- Premium Warming optional, +$20/mo per mailbox
Or grow managed SMTP volume
Move to managed sending infrastructure with warming and inbox protections built in. The Business plan starts at one managed sender doing 200/day, then grows in clear, published tiers.
- Base: one managed sender · 200/day
- Warming + Postmaster / DMARC monitoring
- Inbox placement testing
- Volume grows in published tiers (below)
On Business, grow managed sending volume in published tiers:
Single and Team scale by adding mailboxes; only the Business plan is open-ended — managed SMTP volume grows past Team in published tiers.
Why we're built differently.
No new system to learn.
Most cold email tools bolt AI onto a dashboard. We built the whole thing for your Claude or ChatGPT to drive — no menus, no custom objects, no enrichment tables to maintain. Your AI handles the complexity; you stay in the conversation.
Run with your AI, not by it.
Some AI tools send on your behalf, unsupervised. We don’t. Your AI plans, drafts, and orchestrates — and you see every email before it goes out. Same agent leverage, none of the autonomy risk.
Strategy from years of doing this for real.
The advice your AI gives isn’t generic. It comes from the team behind senders.co — outbound for 200+ B2B companies — distilled into a playbook your AI reads and applies to you: who to target, how to sequence, how to write email people actually answer.
Built deliverability-first.
Every recommendation is shaped by deliverability know-how — warming, domain health, sending limits, spam-risk checks — so growing your outbound protects your reputation instead of burning it.
What operators say.
Bringing a vast knowledge base and B2B data sourcing directly into Claude makes strategy and market sizing a breeze.
We went from setup to sending in just a few clicks, and because it lives inside my Codex there is no training or additional context required.
I can just talk with my agent in English, and my agent can set up campaigns, A/B testing, pull down contact data and more. Plus it does the heavy lifting of keeping me out of the spam folder.
Built by the team behind senders.co — our deliverability and cold-email consultancy, with 200+ client engagements, every shape and size. Senders.ai is that practice, turned into software your AI can run. See the case studies →
Questions worth answering up front.
MCP (Model Context Protocol) is an open standard that lets an AI assistant connect to outside tools and act on them. Senders.ai is an MCP server: once you add it to Claude or ChatGPT, your AI can call real Senders.ai tools — research a domain, verify emails, build a list, send a campaign — right from your conversation. Nothing to install beyond pointing your AI at the endpoint.
No. Senders.ai works through Claude, ChatGPT, and other AI assistants you already use. You ask in plain English.
Any MCP-capable client. Today that includes Claude (desktop and web) and ChatGPT (desktop), with more AI apps adding MCP support. If your assistant supports MCP, Senders.ai works.
We're not a fully-autonomous AI-SDR. Your AI works alongside you — it researches, drafts, and orchestrates, and you see and approve every email before it goes out. Same agent leverage, none of the autonomy risk.
Your AI can create a free account on your behalf. Paid plans require you to authorize the payment yourself via a Stripe checkout link — by design. We don’t want AI assistants handling your money.
Yes. Bring a list you already have and your AI will verify and clean it before anything sends, or have it build a fresh one for you with research and prospecting. Either way works.
Cancel anytime — no contract and no lock-in; your plan simply stops renewing at the end of the billing period. How your data is handled is covered in our Privacy Policy.
No. Senders.ai is built for B2B teams sending tens to hundreds of legitimate, considered emails a day. If your model depends on burning through disposable domains, we’re not for you — by design.
