M for Mercury

More interested leads from every LinkedIn sender you run.

Mercury finds the people worth talking to, researches each one, writes messages that sound like you, and paces every send inside limits LinkedIn tolerates — so acceptance and reply rates climb while your accounts stay safe. Every warm conversation lands in one inbox.

“Saw Northwind just opened a Dublin office — most RevOps teams find their LinkedIn pipeline stalls at exactly that point. Worth a look at how three senders share one inbox?”

Send on autopilot, inside safe limits

Journeys pace every action across your senders, in your working hours. A refusal from LinkedIn is an amber wait, never a failed lead.

And the rest of the workspace

On every plan, with no add-on to buy.

Voice notes, in your own voiceComing soon

Record a script once; Mercury writes each note from the same research and records it personally, then sends it as a journey step.

Advanced analytics

Acceptance, replies and positives across campaigns, senders and audiences — one definition of a positive reply everywhere.

Audience analytics

Who accepts and who replies — by title, seniority, industry, company size and country — so you cut the segment that was never going to answer.

Customer 360

One row per human being — tags, journey position, every conversation across every sender, your notes. No duplicate people.

Two-way CRM sync

Leads flow in from HubSpot, Salesforce, Attio or Zoho and results flow back — deletions included — so the two never argue about who exists.

Programmable — API, CLI & MCP

Every object you can click, you can call. Webhooks push events as they happen, and the MCP server lets an AI agent run outreach under the same limits.

The screens on this page are illustrations. The numbers in them are examples — your workspace shows your own.

Safety

Built to keep your accounts, not just to send from them.

A restricted LinkedIn account costs more than any tool saves. Mercury treats pace as the product.

Limits that behave like a careful human

Every sender gets separate daily caps for invitations, messages and profile views. Steps only run inside the workspace’s working hours, in the workspace’s time zone, and the same clock gates every sender — there is no way for a campaign to “catch up” at 3 a.m.

  • Daily limits per sender, per action — hitting one is the limiter working, so it is never shown as an error
  • Working hours per workspace, with an all-off day meaning closed
  • Acceptance sweeps that retire stale invitations after 30 days
  • When LinkedIn refuses an action, the sender waits in amber and the lead is untouched

Every reply, one inbox

Conversations from all your senders land in one place and stay in step with LinkedIn — a thread that had fifty-five messages on LinkedIn shows fifty-five here. A reply stops the journey for that person on the spot, and a positive one is flagged for whoever is on the inbox.

  • Send as any connected sender; every message carries who sent it
  • Positive replies pushed to HubSpot, Salesforce, Attio or Zoho
  • Slack and in-app notifications the moment a thread turns warm

Know how it is going before anyone asks

The Mercury Score turns acceptance, reply and positive rates, sender health and provider limits into one number, benchmarked absolutely rather than against last week. The Executive Report puts the same numbers on a page you can share by link or embed for a client — the Score stays private to you.

  • Week, month or quarter, per campaign or per workspace
  • Share links and embeds that need no login
  • Audience analytics: who accepts, who replies, by title, industry and country

Results

The numbers a founder or a client actually asks for.

Mercury reports outreach the way it is judged: did they accept, did they reply, was it a yes, did it become a meeting.

Acceptance ratePer sender, per campaign

Invitations accepted against invitations sent, swept fairly so every sender is checked and stale invites are retired.

Reply rateEvery thread counted

Replies against first messages, reconciled with LinkedIn so a reply that arrived while nobody was looking is still a reply.

Positive repliesOne definition

A single, confirmed rule for what counts as a positive — used by the dashboard, the report and the CRM push alike.

PipelineMeetings and stages

Tag a person as a meeting, a proposal or a customer and Customer 360 and the report move with them.

Figures shown in the illustrations on this page are examples. Your Executive Report shows your own.

Who it is for

Agencies, sales teams and the people who build on top of them.

Agencies

Run each client in its own workspace under one subscription: their senders, their audiences, their inbox — and a client portal login that can look but never touch. Share the Executive Report by link instead of writing the Friday email.

Sales teams

Rotate outreach across the whole team’s LinkedIn accounts, keep every conversation in one inbox, and push the positives straight into HubSpot, Salesforce, Attio or Zoho with the activity logged.

Builders

Everything in the app is on the API — on every plan. Webhooks for replies and acceptances, a CLI (npm i -g @mformercuryy/cli), and an MCP server so your AI agents can run outreach with the same limits as a person.

Questions

Before you buy

What counts as a sender?

A LinkedIn account you connect to Mercury and send from. Three teammates’ accounts are three senders; one account used by three teammates is one. Starter is sold for one to five senders, Pro for one to twenty-five, and Agency includes twenty-five with more at $19 each.

How do I pay, and when does my workspace open?

Choose a plan and a sender count, enter your details and we raise an invoice through Veem — pay it by card or bank transfer in Veem’s own checkout. The moment Veem authorises the payment, the checkout page gives you a one-use link to create your account. Card payments are usually authorised in minutes; bank transfers take longer.

Is my LinkedIn account safe?

Mercury is built around not losing accounts. Every sender has separate daily limits for invitations, messages and profile views; steps run only inside working hours; and when LinkedIn itself refuses an action the sender waits rather than retrying. You connect through a hosted LinkedIn login window, so your password is never stored by Mercury.

Can I add senders or change plan later?

Yes. Adding senders or moving between Starter, Pro and Agency is a new invoice for the difference; write to us from your workspace and it is done the same day. We are building self-serve upgrades next.

Is there a free trial?

No — every workspace opens on a paid plan, monthly or yearly. Monthly plans do not renew automatically: you are invoiced before the period ends and can simply not renew. If Mercury is not right for you in the first fourteen days, tell us and we will refund the first month.

Do I need a work email?

Yes. Workspaces are opened with a company address; personal and disposable mailboxes are refused at checkout and again at sign-up. Teammates and client-portal logins you invite from inside the workspace are not held to this rule.

What are Mercury Coins and Contact Credits?

Coins pay for AI — message writing, AI audience columns, review loops. Contact Credits pay for data — Find Contacts searches and verified emails. Every plan includes a monthly allowance of both; top-ups are on the pricing page and never expire while your plan is active.

Ready to run outreach you don’t have to babysit?

Pick a plan, pay, and connect your first sender in about ten minutes.
