Wanna / AI customer follow-up email tools
Is there an AI that writes and sends follow-up emails to my customers? 7 tools
Written by Wanna AI. Checked on 23 Oct 2026, refreshed every 30 days. Wanna is our product and is in this list. Prices change; open each link before you decide.
Short answer. Yes, but the tools split into three kinds, and only some of them send. Some chase one thread from your own Gmail until the customer answers (autoremind.ai; CloseReply sends one 24-hour follow-up on Pro). Some keep your customer records and draft the follow-up inside them (RadiusOS). Some are email marketing platforms where you build the automation (ActiveCampaign, Brevo). Fyxer drafts replies in your inbox and says it does not send. Wanna is in the list too, with limits we say up front: it drafts for your OK and does not read your customer list. The seven are alphabetical, not scored. We read each vendor's pages on 23 Oct 2026 and ran none of them, except Wanna, which we know from the inside.
How we chose
- The vendor's own pages say the tool writes follow-up or reminder emails to customers, or runs an email automation you can use for that.
- We read each pricing page on 23 Oct 2026. Where a page showed a price only for a billing period or contact count, we print that and say so.
- HubSpot and Mailchimp are not here: HubSpot's marketing pricing page showed euros and Mailchimp's page did not load for us, and we did not convert or guess a price.
The seven
| Tool | What it writes or sends, from the vendor's page | Who it is for | Price and limits, from the vendor's pricing page, read 23 Oct 2026 | Honest minuses |
|---|---|---|---|---|
| ActiveCampaign | Multi-step marketing automation and AI-powered automation and campaign builders on every plan; generative AI for content from Plus | Owners who will build email journeys for a customer list | "Starts at" per month, billed yearly, for 1,000 contacts: Starter $15, Plus $49, Pro $79, Enterprise $145. Starter: 10,000 email sends a month, 1 seat | Price scales with list size. The page gave a yearly-billed price only; we saw no monthly-billing price. You build the automation; nothing on the page says it follows up a single quote on its own |
| autoremind.ai | Writes the follow-ups and sends them from your own Gmail, in the original thread; stops when someone replies | Owners chasing an answer, a payment or an approval | Free: 3 reminders at once, no card. Starter $4 a month: 10 reminders at once, 1 attachment up to 5MB | Gmail only; the page says Outlook is not supported. Up to 4 messages per reminder. The page's pitch is chasing invoices and contracts, not nurturing a customer list |
| Brevo | An AI content generator for email copy from Starter; forms that trigger a follow-up email on sign-up; multi-step automation workflows from Standard | Small businesses sending campaigns and automated sequences | Free: up to 300 emails a day, per its FAQ. In the page's inline data, USD a month: Starter 9, Standard 18, Professional 499; a yearly price is listed too | Starter starts at 5,000 emails a month. Automation workflows are on Standard, not Starter. You set up each sequence yourself |
| CloseReply | Reads inbound lead emails, replies from your real Gmail, and says it sends a follow-up if there is no reply in 24 hours, on Pro | Owners who miss inbound leads, in trades, clinics and similar | Per month, 7-day trial: Starter $149, Growth $299, Pro $499 | Built for replying to people who wrote to you first, not for writing to your past customers. Auto follow-up (24h) is on Pro only, $499 a month; the Growth card lists it unchecked and the Starter card does not list it |
| Fyxer | Drafts replies in your tone and keeps a follow-up list from your meetings and email. Its FAQ says it does not send: you decide what goes out | People who chase clients from one inbox | Free: $0, 400 credits a month (about 20 chat messages). Pro $49 per person a month or $37 per person a month billed yearly. Team $99 per person a month or $64 per person a month billed yearly. 14-day trial on Pro and Team | Drafted replies start on Pro. Credits meter the work; the page shows an unlimited-credits offer for the first 3 months. Works with Gmail and Outlook |
| RadiusOS | Keeps customers on a board and drafts follow-ups in your voice, learned from your sent email; Pro adds 5 pre-written follow-ups each night and follow-ups that stop when someone replies | Solo owners, trades and realtors who want one place for customers | Per month: Free $0 (50 customers, 30 AI credits). Pro $19 (1,000 customers, 300 credits). Business $39. Team $69 | You move your customers into it (CSV or vCard import). Follow-ups that stop on reply and drafts in your voice are not on Free. We read the pricing page and ran none of the drafts |
| Wanna | Drafts letters and follow-ups for your OK. When you switch sending on, a letter goes from your own connected domain | A founder unsure of the next task | Free: plan, matches, first drafts. Starter $20 a month, 200 credits. Growth $49, 5,000 credits. Scale $149, 16,000 credits | Does not read your customer list or notice who went quiet. Sending is off for every new company until you turn it on (Trust). Early: 4 companies, 0 paying, 0 things sent outside in 7 days (live) |
By job
Chasing one answer, payment or approval from your own Gmail: autoremind.ai. Replying to new leads fast and following up if they go quiet: CloseReply (follow-up on Pro). Follow-ups drafted from a customer record: RadiusOS. A list of customers you email on a schedule: ActiveCampaign or Brevo. Drafts in your own inbox that you send yourself: Fyxer.

What Wanna is and is not
Wanna writes letters and follow-ups and they wait for your OK (approve or autonomous). A letter goes out only after you turn on "Let me write outside for you" and connect a separate sending domain with your name and postal address in the footer, up to the daily limit you set. Every letter has an unsubscribe link, people who say no go on a stop-list, and nobody gets the same letter twice (what it does). In Autonomous mode it sends first letters to people already in your Outreach; a letter it finds risky waits for you.
It does not read your customer list or a CRM, does not notice which customers went quiet, does not send from your Gmail inside the original thread and does not stop a sequence when someone replies. If you want that, the tools above come closer. On the live page at 10:44 UTC on 23 Oct 2026: 4 companies of people, 0 paying, MRR $0, 0 things that went outside in the last 7 days. That is a small base, and no follow-up case study is on record. To see what it would draft for your company, start free.
What this list does not replace
It does not replace your own call to a customer who has gone quiet: a tool can send a nudge, not learn why nobody answered. It does not replace reading every draft before it goes out; we read pricing pages and did not test any vendor's drafts. It does not replace a check of the rules for email to customers where you sell, or of each vendor's data terms before you connect a mailbox. See the limits of letting AI act for a company.
FAQ
Is there an AI that writes and sends follow-up emails to my customers? Yes. autoremind.ai writes and sends from your own Gmail, and CloseReply says it sends a follow-up after 24 hours of silence on its Pro plan. RadiusOS drafts follow-ups from a customer record, and ActiveCampaign and Brevo run automations you build. Fyxer drafts but does not send.
Can AI send a follow-up from my own Gmail? autoremind.ai says it sends from your own Gmail, in the original thread. CloseReply says replies come from your real Gmail. Fyxer says it does not send for you.
Will it stop following up when my customer replies? autoremind.ai says it stops when someone replies, and RadiusOS lists follow-ups that stop on reply on Pro. We did not find that statement on the other pricing pages.
How much do AI follow-up email tools cost? autoremind.ai has 3 free reminders and then $4 a month. RadiusOS Pro is $19 a month, Brevo Starter is 9 and Standard 18 in its page data, and CloseReply's auto follow-up is on Pro, which is $499 a month (Starter is $149).
