Best AI Email Assistants for Follow Up Boss Users
Samih Sghier, FounderPublished November 11, 2026
If your leads write in by email, the best AI email assistant for Follow Up Boss is InboxPilot (we make it). It reads the whole conversation in Gmail or Outlook, adds the lead's Follow Up Boss record, and writes the reply.
If you work your database from inside the CRM, Follow Up Ace is the better choice. If your leads pick up the phone, look at Carly.
Prices are the cheapest plan with AI, from each vendor's pricing page on November 11, 2026. We did not run paid trials, so what we say about other tools comes from their own pages, linked below.

Our pick: InboxPilot
InboxPilot connects to the Gmail or Outlook inbox your leads write to, and to Follow Up Boss with an API key. Each reply uses the thread plus the lead's stage, source and the homes they asked about, which is what makes a fast first reply useful.
Replies start as drafts, and you choose which ones send on their own. Follow Up Boss activity can start an email too, such as an offer to show a home a lead keeps viewing.
Before each automated email, it checks what Follow Up Boss shows for that lead and holds the email if a drip campaign or action plan just reached them.
Starter is $39 a month after a 7-day free trial, with auto-replies. There's no free plan.
We built it for agents and small teams who answer leads by email. If you work mostly by phone or text, it isn't for you: it doesn't call, text or score leads, and it can't change stages or tags in Follow Up Boss.
It has no Fair Housing check, so read what it writes before you let it send. It can only hold around emails Follow Up Boss records. Follow Up Boss doesn't list it in its integrations directory yet.
How AI email reaches the Follow Up Boss timeline
Follow Up Boss logs email through its own connection to your mailbox. So the test for any AI tool is where it sends from. The connected Gmail or Outlook account gets logged, and a separate sending service may not.
We ran that test in November 2026 on a Follow Up Boss account of our own. Emails sent from the connected Gmail inbox appeared on the lead's timeline within about a minute, and the lead's replies joined the same thread.
You can check any tool here the same way. Send one email to a contact saved in Follow Up Boss, then open their timeline.
Built for Follow Up Boss
Follow Up Ace: working your database inside the CRM
Follow Up Ace is built only for Follow Up Boss, and it goes deeper into the CRM than anything else here. It writes a Win Score and Churn Risk onto your contacts, ranks who to work next, and drafts the follow-up for you to review and send.
It's ahead of us on compliance and CRM access. Its automated sends get a Fair Housing scan, its Claude and ChatGPT connector offers up to 193 tools, and it has an iPhone app.
The free tier allows 15 AI messages a day. Ace is $25 a seat a month, Ace Pro with the connector is $55, and Autopilot outreach is an add-on from $49 a month.
It works from your CRM data and not your mailbox, by design. Of its Gmail access, the company writes:
"It does not read your inbox."
If you'd rather no AI read your mail, that counts in its favor. Its pages describe outbound follow-ups, not answers to incoming email.
Pick Follow Up Ace if you spend your day in Follow Up Boss working a list of people to contact.
Smart Messages: suggestions inside Follow Up Boss
Smart Messages is Follow Up Boss's own AI. It suggests texts and emails from the lead's activity, and you pick what to send from inside the CRM. There's nothing extra to connect, and it covers texts, which we don't.
There's no extra charge for it. Follow Up Boss starts at $69 a user a month, or $58 billed annually, though the company says many AI features rely on data from its paid Calling add-on.
Pick Smart Messages if you already work leads from inside Follow Up Boss and want help writing each message.
AI assistants that live in your inbox
Fyxer: one person's Gmail or Outlook
Fyxer drafts replies in your tone, labels new email in Gmail or Outlook, and takes meeting notes, which we don't. Its site says over 25,000 companies use it. Pro is $49 a person a month, or $37 billed annually, and the free plan doesn't draft.
Its pricing page lists no Follow Up Boss connection, so a draft can't see a lead's stage or the homes they asked about. Send from the mailbox Follow Up Boss syncs and the reply should still reach the timeline.
Pick Fyxer if your inbox is mostly clients and colleagues and you want meeting notes in the same tool. Our Fyxer alternatives guide goes further on it.
Superhuman Mail: a faster email app
Superhuman Mail is a separate app for Gmail and Outlook accounts, built for getting through a busy inbox fast. Pro is $15 a member a month, or $12 billed annually, the cheapest paid plan on this list, and its Email Assistant drafts replies. Business, at $40, adds writing that matches your voice.
Its CRM connections are HubSpot, Salesforce and Pipedrive, so drafts carry no Follow Up Boss data.
Pick Superhuman Mail if you want a faster email app and don't need lead details in your drafts.
alfred_: client threads and a morning brief
alfred_ triages email, drafts replies and tracks follow-ups across Gmail, Outlook, iCloud and IMAP accounts, more account types than we support. Its morning brief lists who needs a callback. Starter is $29.99 a month, or $25 billed annually.
It connects to HubSpot and Salesforce. Its own real estate guide pairs it with Follow Up Boss for leads, so the two run side by side.
Pick alfred_ if you juggle active deals across several accounts and want a daily list of who to chase.
If you want calls and texts handled
Carly: phone-first lead handling
Carly calls new leads within about a minute, books showings and tracks contract deadlines, then writes calls, texts and outcomes back to Follow Up Boss. We do none of that by phone. Its AI agents start at $35 a month.
Pick Carly if your leads answer the phone faster than they answer email. A 30-day real estate lead follow-up schedule shows how to split the work across channels.
If you would rather build it yourself
Zapier with an AI step: your own workflow
Zapier connects Follow Up Boss and Gmail with triggers such as a new contact or a stage change, and actions such as creating a draft reply. It's the most flexible option here, and it can update Follow Up Boss records, which we can't.
Pro starts at $29.99 a month for 750 tasks, or $19.99 billed annually, and AI steps use tasks too. You write the prompts and keep each flow running, and our inquiry reply templates are a good base for them.
Pick Zapier if you like building your own automations and want full control. Nothing checks whether a drip just went out unless you build that step.
