Here is a statistic that should make anyone who sends important emails uncomfortable: 80% of deals require 5 or more follow-up touchpoints, but 92% of people stop following up after 4 attempts. The math is simple, most people quit right before the finish line. And this is not just a sales problem. Every unanswered email to a colleague, every proposal waiting for approval, every scheduling thread that went silent represents potential value leaking through the cracks.
Our pick for email follow-ups in 2026 is alfred_, which we build. It tracks which of your sent emails still have no reply, shows them to you each morning, and drafts a follow-up when you ask. But follow-up tools range from simple reminders to full sales engagement platforms, and the right one depends on whether you are tracking personal conversations or running outbound campaigns. Here is how seven tools compare.
The Problem: Follow-Up Failure Is a Revenue and Relationship Leak
The data on follow-up behavior is striking:
- 98% of sales are NOT made at first contact, only 2% close on the first touch (IRC Sales Solutions)
- 80% of deals require 5+ touchpoints, but 48% of reps give up after just one attempt (Belkins)
- 3x higher reply rate with 4-7 follow-up emails (27%) versus 1-3 emails (9%) in a sequence (Woodpecker)
- 21x more likely to qualify a lead if you follow up within 5 minutes versus 30 minutes
- 700% increase in meaningful conversations when following up within 1 hour (Momencio)
- $600,000/year in lost revenue at a 10% close rate with 250 missed leads. That is $50K/month walking away (GreenLight Studio)
- 29% revenue increase for companies that track follow-up performance metrics (SalezShark)
And these stats focus on sales. The follow-up problem is equally damaging in non-sales contexts: the performance review feedback that never got a response, the partnership proposal that died in someone’s inbox, the vendor quote that expired because nobody circled back. The average salesperson makes only 2 follow-up attempts. Most professionals make even fewer on non-sales threads.
The tools below take three distinct approaches: reminders (you write the follow-up), sequences (pre-written messages sent on schedule), and AI-assisted (the tool tracks what is unanswered and helps you draft).
Quick Comparison: 7 Follow-Up Tools
| Tool | Price | Approach | Key Limitation |
|---|---|---|---|
| alfred_ | From $29.99/mo | Finds unanswered sent email when asked + drafts on request + calendar | No sequence automation for cold outreach |
| Superhuman | $30–$40/mo | Auto-detection + AI draft suggestions | No CRM, no multi-step sequences |
| Boomerang | $4.98–$49.98/mo | Manual reminders + send later | No AI detection, no auto-drafts |
| FollowUp.cc | $18/user/mo | BCC-based reminders + response detection | No AI, reminder-only, Gmail only |
| Mixmax | Free–$129/user/mo | Multi-step sequences + tracking | Sales-focused, Gmail only, expensive |

Deep Dive: Each Tool Reviewed
alfred_: from $29.99/month
alfred_ is an AI assistant for client-facing teams, and each person on the team gets their own. It keeps a list of the replies you owe, finds who you’re still waiting on when you ask, across up to six Gmail, Outlook and IMAP accounts, manages your calendar and sends a morning brief by email or text. For follow-ups, it finds the threads in your sent mail where the other person has not answered, when you ask, or every Monday with the Chase what I’m owed routine. When you want to follow up, ask for a draft: it is written from the thread itself, not from a template. You review and send.
The replies you owe show up in your morning brief, next to the meetings ahead. Ask “who hasn’t answered me this week?” and you get the other side, with a draft follow-up when you want one. How the tracking works, and what counts as waiting on you versus waiting on them, is in Follow-ups: threads waiting on a reply.
Plans start at $29.99/month, in the range of Superhuman ($30+) and Mixmax ($29+) and below Streak ($49+). It works with both Gmail and Outlook. The tradeoff: alfred_ is not built for cold outreach sequences. If you need to send 1,000 templated follow-ups to prospects, tools like Mixmax or Saleshandy are purpose-built for that. alfred_ is for the follow-ups that matter in relationships you already have.
| Superhuman | alfred_ | |
|---|---|---|
| Detects sent emails with no reply | Yes | Yes |
| Drafts the follow-up | Yes, automatically | Yes, when you ask |
| Surfaces follow-ups in a morning brief | No | Yes |
| Calendar management | Basic | Yes |
| Requires switching email client | Yes (Superhuman app) | No (works on Gmail and Outlook) |
| Providers | Gmail, Outlook | Gmail, Outlook |
| Price | $30–$40/mo | from $29.99/mo |
Superhuman: $30–$40/month
Superhuman’s follow-up feature automatically detects when a sent email has not received a response and generates a follow-up draft in your voice. You can configure this for all messages, external only, or off entirely. Combined with read receipts (so you know if the original was opened), snooze with natural language scheduling (“remind me Monday 9am”), Superhuman covers follow-ups inside its own app.
Superhuman handles making follow-up detection effortless. You do not set reminders, the system identifies what needs attention and prepares a draft. The read receipt context is valuable: knowing your email was opened but not replied to changes your follow-up tone compared to knowing it was likely missed.
At $30/month (Starter) or $40/month (Business), Superhuman is expensive for follow-up tracking alone. There is no CRM integration, no multi-step sequence automation, and no calendar management. Follow-up drafts are suggestions you review and send, not automated sequences. Gmail and Outlook only.
Boomerang: $4.98–$49.98/month
Boomerang pioneered the “boomerang” concept: send an email, set a reminder time, and the email returns to your inbox if you have not received a reply. Send Later scheduling lets you compose emails now and send them at optimal times. Inbox Pause blocks new messages during focus periods. The Respondable feature (premium) rates the likelihood that your email will get a reply before you send it.
Boomerang is the most affordable entry point for follow-up tracking. The Personal plan at $4.98/month (annual) gives you basic credits, and the Pro plan at $14.98/month adds more. The Respondable feature is unique and genuinely useful for crafting better initial emails that reduce the need for follow-ups.
The fundamental limitation is that every follow-up requires manual setup. You set the reminder for each email individually. There is no AI detection of which conversations need follow-up. When the reminder fires, you write the follow-up yourself. No auto-drafts, no calendar management. The free plan is very limited at 10 credits per month. Boomerang works with Gmail and Outlook.
FollowUp.cc: $18/user/month
FollowUp.cc uses a clever BCC-based system: when sending an email, you BCC an address like followup1day@followup.cc or followup1week@followup.cc, and you will receive a reminder at that interval if no reply arrives. Response detection automatically cancels reminders when the recipient replies, avoiding awkward double-follow-ups. A Chrome extension adds Send Later and snooze functionality.
The simplicity is the strength. There is nothing to learn beyond adding a BCC address. Response detection is a thoughtful feature that most reminder tools lack. The calendar feed integration lets you see pending follow-ups in your existing calendar.
FollowUp.cc is a reminder-only tool. There is no AI, no draft generation, no email triage. The BCC system requires you to decide at send time which emails need follow-up tracking. There is no after-the-fact detection. The Chrome extension limits usage to Gmail. At $18/user/month, it is more expensive than Boomerang for a narrower feature set, though the BCC approach requires less friction in practice.
Mixmax: Free–$129/user/month
Mixmax is a sales engagement platform that turns Gmail into an outbound machine. Multi-step email sequences automatically send follow-ups on a schedule, with branching logic based on whether the recipient opened, clicked, or replied. Embedded polls, surveys, and CTAs track engagement. Meeting scheduling, CRM integrations (Salesforce, HubSpot), and detailed analytics round out the platform.
For sales teams running structured outbound campaigns, Mixmax is powerful. The sequence builder is flexible, conditional triggers are sophisticated, and the CRM integrations mean follow-up data flows into your pipeline tracking automatically.
Mixmax is not personal email management. It is built for sales workflows. Mixmax now has one paid plan priced by how many people you add to sequences each month: free for 50 recipients, $29/user/month for 100, $89 for 1,500 and $129 for 3,000, billed yearly. Gmail only. For a heavy sales cadence it gets expensive. For individual professionals tracking personal follow-ups, Mixmax is overkill. For sales teams, it is a strong contender.
Streak: $49–$159/user/month
Streak is a full CRM that lives inside Gmail. Pipeline tracking, email tracking, mail merge, and contact management happen without leaving your inbox. The AI Co-Pilot (available on Pro+ at $89/user/month monthly, or $69/user/month annual) assists with follow-ups by analyzing deal context and suggesting next steps. Pricing varies by billing cycle: $49/$69/$129 per user/month on annual plans, or $59/$89/$159 per user/month on monthly billing.
The pipeline view is unique for follow-up tracking. Every email thread maps to a deal stage, so you can see at a glance which conversations are active, which are stalled, and which need follow-up. For sales teams managing deal flow entirely inside Gmail, this visual pipeline is powerful.
Streak is very expensive, $49/user/month minimum (annual), and AI features require the Pro+ tier ($69/user/month annual, $89/user/month monthly). It is CRM-focused, not email management. There is no AI email triage, no auto-drafting of follow-up replies (the AI Co-Pilot suggests, it does not draft), and no calendar management. Gmail only. AI credits are limited per billing period. For teams that need a Gmail-native CRM, Streak is strong. For individual follow-up tracking, it is overkill and overpriced.
Saleshandy: $25–$209/month
Saleshandy is built for cold outreach at scale. Automated multi-step email sequences with conditional follow-ups (triggered by opens, clicks, or replies) can send up to 6,000 emails per month on the Starter plan. Personalization fields let you customize at volume.
For outbound sales teams doing high-volume prospecting, Saleshandy offers serious capacity at competitive pricing. The Outreach Starter at $25/month (annual) sends more emails than most teams need, and conditional triggers add sophistication to sequences.
Saleshandy is a cold outreach tool, period. It does not manage inbound email, does not provide AI triage, has no calendar integration, and is not designed for relationship-based follow-ups. The Starter plan lacks subsequences, CRM integrations, and API access. If you need to follow up on a proposal with an existing contact, Saleshandy is the wrong tool. If you need to prospect 10,000 cold leads with automated sequences, it is purpose-built.
How We Would Set It Up
The right follow-up stack depends on your use case:
For professionals managing relationship-based follow-ups:
- alfred_ (from $29.99/month) for tracking unanswered threads, with drafts on request and your calendar in the same place
- This covers proposals, client conversations, internal requests, scheduling threads, and any email where the follow-up needs to be personal and contextual
For sales teams running outbound sequences:
- Mixmax ($29/user/month+) or Saleshandy ($25/month) for multi-step automated sequences
- alfred_ (from $29.99/month) for keeping track of the replies and relationship follow-ups that sequences generate
For budget-conscious individuals:
- Boomerang Personal ($4.98/month) for basic send-later and reminder functionality
- Upgrade to alfred_ (from $29.99/month) when the cost of missed follow-ups exceeds the subscription price, at 2% of sales closing on first contact, that threshold is low
The Bigger Picture: Follow-Ups Are Where Revenue Lives
The follow-up gap is not a technology problem. It is a willpower and memory problem. People know they should follow up. They intend to follow up. But at 121 emails per day, the thread from three days ago that needs a nudge gets buried under 363 newer messages. By the time you remember, the moment has passed.
The tools that solve this best are the ones that remove memory and willpower from the equation. Boomerang and FollowUp.cc offload memory (reminders). Mixmax and Saleshandy offload willpower (automated sequences). alfred_ offloads the memory: it tracks what is still unanswered and drafts the follow-up when you ask, and you keep the judgment of review-before-send. If you only want the detection half, the narrower comparison is which tool tracks emails you are still waiting on a reply to.
alfred_ plans start at $29.99/month, about the same as Superhuman ($30) and Mixmax’s entry plan ($29), and below Streak ($49+).
