How it works

Your Gmail AI appointment setter, live in four steps

Connect Gmail

Add your Gmail or Workspace address with a Google app password. Recent mail syncs in as context.

Teach it your offer

Add your services, pricing and booking link to a knowledge base, and write how you qualify a lead.

Review before it sends

Approve each reply first, or have it write drafts in your Gmail to send yourself.

Let it run

Switch to auto once you trust it. Every reply, label and follow-up stays on the record.

01 · Reply

Replies in the same Gmail thread, in your voice

Every new inbound email is handed to your setter agent, which reads the whole thread and answers it with proper In-Reply-To and References headers, so the reply sits right under the lead's message in Gmail. Characters give it your tone, and your knowledge base gives it the facts.

  • Threaded replies from your own address, not a no-reply bot
  • Answers grounded in your services, pricing and policies
  • Business hours per inbox, with a holding message after hours
  • Never replies to no-reply senders, receipts or newsletters

02 · Draft mode

Start with drafts in your Gmail, graduate to autopilot

Not ready to let an AI send email from your address? Tell the setter to draft instead of send, and its replies land in your Gmail Drafts folder, under the lead's thread, for you to tweak and send. Or keep it in draft autonomy, where every send waits in Approvals. When the drafts stop needing edits, switch the agent to auto.

  • Real drafts in your Gmail Drafts folder, in the right thread
  • Or every send waits in Approvals while labels and lookups run
  • Approve, edit or reject from one queue across inboxes
  • Switch suggest, draft or auto per agent, instantly

03 · Book & follow up

Gets the meeting booked, then chases the ones who go quiet

Once a lead is qualified, the setter sends your booking link at exactly the right moment, or books directly through a custom tool connected to your scheduling API. Threads are labelled as they move, and a follow-up sequence nudges leads who stop replying, stopping the moment they answer.

  • Your booking link sent only once the lead qualifies
  • Or book through your scheduling API with a custom tool
  • Gmail labels like Qualified and Booked applied as it goes
  • Follow-ups written fresh each time, sent inside business hours
After the booking link is sent, a follow-up goes out on day 2; the lead replies on day 3, so the day 5 follow-up is cancelled and the thread is labelled BookedDay 0Day 2Day 3Day 5Here's my link:grab any slotJust checkingthis reached you!Sorry, busy week!Booked Tuesday.Follow-up 2cancelledsequence stopped: contact repliedFOLLOW-UP SEQUENCE · QUIET LEADSAfter 2 daysFriendly check-in, written fresh from the threadAfter 5 daysLast nudge with one new reason to bookPriya ShahBranding project enquiryLink sentBookedsent inside business hours

What it does inside Gmail

App password sign-in

Connect with a Google app password over IMAP and SMTP. Works for personal Gmail and Google Workspace.

Threaded replies

Replies carry In-Reply-To and References headers, so Gmail keeps them in the lead's thread.

Real Gmail drafts

The setter can write replies into your Gmail Drafts folder instead of sending, so you send them from Gmail.

Gmail labels

Add and remove real Gmail labels, archive and mark as read as the conversation moves.

Knowledge base

Answers come from your services, pricing, FAQs and booking link, not from guesses.

Follow-up sequences

Named nudge sequences for leads who go quiet, stopped as soon as they reply.

FAQ

Gmail AI appointment setter: common questions

How does ReplySetter connect to Gmail?

With a Google app password over IMAP and SMTP. It works for personal Gmail and Google Workspace accounts that allow app passwords (2-Step Verification must be on).

Can the AI book directly on my calendar from Gmail?

Native calendar booking is built for GoHighLevel calendars. On Gmail, the setter sends your booking link once the lead qualifies, or books directly through a custom tool you connect to your scheduling tool's API.

Will it reply to emails already in my inbox?

No. Recent mail is synced so the agent has context, but it only replies to new inbound messages.

Can I review replies before they're sent?

Yes, two ways. In draft autonomy every send waits in Approvals for you to approve, edit or reject. Or tell the setter to draft instead of send, and its replies land in your Gmail Drafts folder for you to send yourself.

Does it keep replies in the same thread?

Yes. Replies are sent from your address with the right threading headers, so Gmail shows them under the lead's original email.

What stops it from replying to newsletters or auto-replies?

Filters and flow conditions decide which emails the agent handles, and it never replies when the latest message in the thread is already yours.

Does it work with Google Workspace?

Yes, as long as your Workspace admin allows app passwords for your account.
