Your prospects reply. So does Replexa.

This could be interesting. Do you have some time next week?

Happy to. How about Tuesday at 10 am or Thursday at 2:30 pm, for a 30-minute video call? Let me know what suits you and I'll send the invite.

The problem and how Replexa solves it

The problem

Anyone can send. Replying is where it falls apart.

A campaign that works creates work. Replies scattered across ten inboxes. “Call me back in January.” “How much is it?” landing at 10 pm.

While you sort through it all, your interested prospect is waiting. And a prospect who waits goes cold.

With Replexa

Every reply is read and sorted, and the follow-up is already written.

All your mailboxes feed into one inbox. The AI agent labels every reply (interested, not now, not interested, out of office) and drafts the next message based on your guidelines.

When a prospect wants to talk, it offers a slot that's genuinely free and sends the invite. You stay in control: require approval or let it send automatically, separately for each type of reply.

Features

From first email to booked meeting, all in one place.

Multi-step sequences, A/Z variants, spintax, time-zone-aware scheduling. That's the baseline. The real gains come after you hit send.

An AI agent that replies

One agent per campaign, with one goal: book a meeting, qualify the lead, share information, or follow your own brief. For each type of reply, you decide whether it answers on its own, prepares a draft for you to approve, or stays out of it.

  • Sandbox: paste a reply and see what it would do. Nothing gets sent.
  • It stops following up once the goal is reached.
  • An unsubscribe request never gets a reply.

Meetings booked straight into Google Calendar

A direct connection, with no Calendly or n8n in between. The agent checks when you're actually free before suggesting a time, checks again right before sending, then creates the event with a Meet link and invites the prospect.

  • Days, hours, duration, buffers and minimum notice: you set the rules.
  • The lead moves to “Meeting booked” on its own.

One inbox for everything

Every sending mailbox in a single list. Each reply shows its interest status, alongside your own labels. Approve the agent's drafts in one click.

  • Subsequences triggered by the reply.
  • Google Workspace, Microsoft 365, OVH, Zoho, IONOS, or any IMAP and SMTP mailbox.

Deliverability essentials

Everything that protects your domains is set per mailbox and per campaign.

  • Daily limits, delay between sends, gradual ramp-up.
  • Mailbox rotation within a campaign.
  • Automatic pause when the bounce rate crosses your threshold.
  • Unsubscribe link, blocklist, custom tracking domain.

Plugged into your tools

HubSpot, Pipedrive and Salesforce stay in sync on their own: a contact is created on the first send and a deal opens when the lead turns positive. The agent can also read from and write to Airtable, or call your own tools.

REST API and MCP

The API mirrors Instantly v2 paths and fields, so an existing n8n workflow switches over with a new URL and key. The remote MCP server lets you run your campaigns from Claude or ChatGPT.

  • OpenAPI 3.1 spec and signed webhooks.
  • MCP with OAuth 2.1, permissions granted workspace by workspace.
  • Around 45 tools: campaigns, leads, inbox, drafts, analytics.

FAQ

The questions we get asked.

Can Replexa replace Instantly?

For sending, the inbox and replies, yes. Import your mailboxes from Instantly's “bulk connect” file, and the API uses the same paths: your n8n, Make or Zapier workflows only need a new URL and key.

What about mailbox warmup?

Not yet. The settings are there, but warmup isn't active. In the meantime, keep your current warmup tool running on your mailboxes. Replexa takes care of sending and replies.

Can the agent send an email without my approval?

Only if you decide it can. For each type of reply (positive, neutral, negative), you choose: it replies on its own, it prepares a draft for you to approve, or it doesn't reply at all. An unsubscribe request never gets a reply.

Which mailboxes can I connect?

Google Workspace, Microsoft 365, OVH (MX Plan and Email Pro), Zoho, IONOS, and any mailbox reachable over IMAP and SMTP. Bulk import works with a CSV file.

Where is my data stored?

In the European Union, in Ireland. To classify replies and draft answers, the agent sends the reply text to Claude, Anthropic's model. The full list of providers is in our privacy policy.

Is there a free trial?

Yes, 7 days on the Growth plan. Your card is required when you sign up, but nothing is charged until the trial ends, and you can cancel before then. Starter and Scale are billed from the day you subscribe.

Can I cancel anytime?

Yes. The subscription is monthly and you cancel it from the app. It ends at the close of the period you've already paid for, and you can export your data beforehand.

Does it work with Claude or ChatGPT?

Yes, through the remote MCP server. Add it as a connector, choose the workspace and permissions, then read your replies or launch a campaign right from the conversation.

Your next interested prospect deserves better than “I'll get to it tomorrow.”
