UnlimitedMailboxes and warmup

Cold email that reaches the inbox.

Zexr warms every mailbox in a shared pool, sends your campaigns inside deliverability guardrails, and brings every reply into one inbox, where an AI agent answers from your sales playbook.

Free plan warms 10 mailboxes · No credit card

Everything you need to run cold email.

Connect your mailboxes, warm them up, send campaigns and handle the replies, all from one dashboard.

One inbox for every reply

Replies from all your mailboxes arrive in one place, already labeled as interested, out of office, a question or an unsubscribe.

Emails that read as personal

Write each step with variables like first name and company, test two versions against each other, and draft or rewrite with AI.

A pipeline for your deals

Move interested leads from reply to meeting to closed on a simple board.

Campaign analytics

Sends, replies and bounces for every campaign and every mailbox.

API, webhooks and MCP

Scoped API keys, signed webhooks and an MCP server for your own tools and AI clients.

How it works. Zexr keeps your mailboxes healthy while you send.

01

Connect your mailboxes

Add Google Workspace, Microsoft 365 or any SMTP and IMAP account. Zexr checks your domain's SPF and DMARC records and shows the health of every mailbox.

Learn about sending
02

Warm them up

Each mailbox exchanges a small amount of real email with other inboxes, starting at 10 a day and growing slowly. This builds the reputation it needs before your first campaign.

03

Send your campaigns

Build a sequence, add your contacts and choose your sending hours. Zexr spreads the emails across your mailboxes, with a daily limit and a pause between sends for each one.

04

Watch your deliverability

See how much of your mail lands in the inbox at Gmail, Outlook and Yahoo. If a mailbox starts going to spam, Zexr lowers its volume before it affects the others.

Automations

When this happens, do that.

Every reply, booked meeting, bounce and warmup dip is a trigger. Wire it to your stack on a canvas: branch on intent, post to Slack, open the deal, update the CRM. The one below is running its test right now. Press Test in the window to fire it again.

Branch on anything

Split on reply intent, confidence, where a contact came from or any field the event carries. Yes goes one way, no goes the other.

Act inside Zexr and out

Open the deal, create a task, label the thread or enrol the contact in a campaign, then tell Slack and update your CRM.

Let AI decide

Ask a yes or no question about the event, or add an AI step that reads the reply and acts, using only the actions you allow.

Test before it runs

A dry run against sample data shows the exact path on the canvas, without sending anything or changing a record.
