# Engage

> Engage is a cold email outreach platform for B2B sales teams, lead-generation agencies and recruiting firms. It connects your Gmail and Google Workspace mailboxes, sends multi-step email sequences inside per-mailbox daily and hourly limits and each lead's local business hours, sorts every reply with AI, and tracks each lead on a pipeline from first email to client.

Engage is email-only and works with Gmail and Google Workspace mailboxes. It does not guarantee inbox placement, does not send LinkedIn messages or SMS, does not sell contact data, and does not run a warm-up network.

## Product
- [Sending & limits](https://site.sisender.com/features/sending): Engage sends from your Google Workspace mailboxes inside daily and hourly limits, paced evenly, in each lead's local business hours, with company lockouts and suppression on every send.
- [AI reply inbox](https://site.sisender.com/features/replies): Engage pulls in replies, labels each one Positive, OOO, Negative or Neutral with AI, moves the lead, and lets you answer on the same thread from the same mailbox.
- [Lead pipeline](https://site.sisender.com/features/pipeline): Drag leads from Replied to Client on a pipeline board and see every send, open, click, reply and stage move on each lead's timeline, with notes and follow-up deadlines.
- [Sequences & A/B tests](https://site.sisender.com/features/campaigns): Build multi-step cold email sequences with merge tags, follow-ups on the same thread, AI rewrites and A/B variants, previews, test sends and per-variant results.
- [Leads & import](https://site.sisender.com/features/leads): Import leads from CSV, skip anyone on your do-not-contact list, filter and bulk-edit leads, and queue missing phone and LinkedIn details for your team to fill.
- [Brands & teams](https://site.sisender.com/features/teams): Run several brands or clients from one Engage workspace, each with its own mailboxes, plus roles and permissions, two-factor sign-in, an activity log and a REST API.
- [A/B testing](https://site.sisender.com/features/ab-testing): Add A/B variants to any step of an Engage sequence, write them yourself or let AI draft two, and compare open and reply rates per variant side by side.
- [AI writing](https://site.sisender.com/features/ai-writing): Improve a subject or body with AI, generate A/B variants, and add a personal first line per lead with the {{aiOpener}} merge tag, using Gemini or your own AI key.
- [Send timing](https://site.sisender.com/features/send-timing): Engage keeps a timezone for every lead and sends only inside their working hours and days, within your campaign window, and shows before launch when campaign and mailbox hours never overlap.
- [Dashboard & insights](https://site.sisender.com/features/insights): See sends, replies, hot leads and the funnel from Sent to Client, with an engagement score per lead and rule-based suggestions on what needs attention, written up by AI when you have a provider set.
- [Unsubscribes & do-not-contact](https://site.sisender.com/features/suppression): Every Engage email carries an unsubscribe link and a one-click List-Unsubscribe header; unsubscribes, opt-out replies, hard bounces and your do-not-contact list are checked before every send.
- [Open & click tracking](https://site.sisender.com/features/tracking): Engage records opens and clicks on each lead's timeline, signs every tracking link, and lets each organisation use its own verified tracking domain instead of a shared one.

## Solutions
- [For lead-generation agencies](https://site.sisender.com/solutions/agencies): Run each client as its own brand with its own mailboxes and campaigns, keep clients from contacting the same lead, and hand interested replies to the right person fast.
- [For B2B sales teams](https://site.sisender.com/solutions/sales-teams): Give SDRs multi-step sequences from their own Google Workspace mailboxes, AI-sorted replies, and a pipeline from first email to closed client.

## Problems Engage solves
- [Cold emails going to spam](https://site.sisender.com/problems/emails-going-to-spam): Cold emails land in spam when a mailbox sends too much, too fast, to bad addresses, or without a working unsubscribe. Here is what to fix, and what Engage controls for you.
- [Gmail sending limits](https://site.sisender.com/problems/gmail-sending-limits): Google Workspace caps how many emails each user can send per day. Engage gives every mailbox its own daily and hourly limits, paces sends and spreads campaigns across mailboxes.
- [Replies getting lost](https://site.sisender.com/problems/lost-replies): When replies are spread across a dozen Gmail inboxes, interested leads wait. Engage pulls every reply into one inbox, labels it with AI and moves the lead.
- [Follow-ups after a reply](https://site.sisender.com/problems/follow-ups-after-replies): Engage cancels a lead's remaining emails when they reply, bounce or are out of office, and keeps follow-ups on the same thread from the same mailbox.
- [Emails at the wrong time](https://site.sisender.com/problems/wrong-time-zone): Emails sent at 3 a.m. local time sit under a pile by morning. Engage keeps a time zone per lead and sends only inside their business hours and working days.
- [Clients emailing the same lead](https://site.sisender.com/problems/client-overlap): Engage locks a lead contacted by one brand from other brands for 90 days, holds the rest of a company for 24 hours after one person is emailed, and skips duplicates at import.
- [Leads tracked in spreadsheets](https://site.sisender.com/problems/spreadsheet-pipeline): Engage keeps every lead on a pipeline from Sent to Client, with a full timeline of sends, opens, clicks, replies and stage changes, notes and follow-up deadlines.
- [Slow answers to hot leads](https://site.sisender.com/problems/slow-follow-up): Engage turns every positive reply into a follow-up task with a response deadline, shows the time left on the lead, and lists hot leads and overdue ones on the dashboard.
