Hunter Changelog

You can now find companies, verify emails, save leads, and launch sequences directly inside ChatGPT. No tab switching, no exports, no copy-pasting. The app is included in every Hunter plan, including Free.

What's new

• Connect your Hunter account to ChatGPT and run your prospecting workflow in plain language.
• Find companies by industry, size, location, or technology. Pull verified contacts inside them, check deliverability before you send, and add leads straight to a sequence, all in one conversation.
• 30+ tools covering the full Hunter API, from search and verification to leads and sequences.

How it works

1. Add the Hunter app in ChatGPT and sign in with your Hunter account. You can also click here to get started.
2. Ask for what you need in plain language. ChatGPT uses the right Hunter tools and shows the results in the chat.
3. Save contacts to a Leads list and launch a sequence without leaving ChatGPT.

Try a prompt

Once the app's connected, give ChatGPT something like:

• Build a prospect list from scratch
  "Find 25 SaaS companies headquartered in Germany with 50–200 employees. For each, find verified email addresses for people in Head of Sales or RevOps roles, and return the results as a table."
• Research an account before a call
  "I have a call with Acme Corp tomorrow. Pull together a briefing: find the company's website and key details, identify the decision-makers in marketing (especially anyone senior), verify their email addresses, and surface any recent context I should know."
• Go from research to sequence
  "Find 30 companies matching my ICP, identify and verify contacts in founder or growth roles at each, save them to a new Hunter Leads list, and prepare a sequence."

Good to know

• Works in ChatGPT on web, desktop, and mobile.
• Available on all plans, including free. Your existing limits and credits apply.
• Uses Hunter's official MCP server with OAuth. ChatGPT only accesses what you permit and never stores your credentials.
• ChatGPT isn't the only assistant Hunter connects to. Claude, Gemini and Grok have first-party setup paths. See Set up Hunter with your AI assistant in one step.

Discover now shows you when new companies match a search you saved, and puts them in front of you ready to work with.

What's new

• Saved searches with new matches appear on the Discover homepage with the exact number of new results, so you can see what changed at a glance.
• Open one and the new companies are at the top of the results and already selected, so you can reveal or save them straight away.
• A new selector at the top of the page lets you take any number of companies at once. If a search returns more than you want, select the first 100.

What to expect

New matches are highlighted and pre-selected only the first time you open the search after they arrive. After that they stay in your results, they are just no longer marked as new.

Open, click, and reply rates in Sequences now measure people instead of individual emails, giving you a more accurate picture of how your audience actually engages.

What's changed

• Open, click, and reply rates now count distinct recipients who engaged, divided by recipients who received: "what fraction of people did X" rather than "what fraction of emails got X."
• This applies everywhere these rates appear: the Sequences list, sequence stats, CSV export, reporting overview and detail tabs, the API, and MCP tools.
• Unsubscribe rate is now recipient-based too.

What to expect

• On multi-step sequences, these percentages will go up: the more steps, the bigger the change. Single-step sequences are unaffected.
• Bounce rate and successful rate are unchanged (still per-delivery, since they're SMTP events). Step-level numbers, graphs, and leaderboards are also unchanged.
• For API users: per-step counts no longer sum to the recipient-based totals at the sequence level.

Why it matters

The old message-based method deflated rates on multi-step sequences: 10 replies across a 4-step, 100-person campaign showed as 2.6% when 10 of your 100 people actually replied. Recipient-based rates report that as 10%, so your numbers reflect real audience engagement.

We've launched two new features that cover the full setup for professional outreach: managed email account provisioning and automated inbox warm-up.

Managed email accounts

You can now buy domains and create pre-configured email accounts directly within Hunter — no external email provider or manual setup required.

How it works:

• Buy a domain and create email accounts within Hunter in just a few steps
• Accounts are typically ready within 1 hour, with SPF, DKIM, and DMARC fully configured
• Choose your domain, sender name(s), and number of accounts per sender during setup
• Accounts marked as Active are immediately available for use in Sequences

Inbox Protection

Inbox Protection automates email warm-up to help you build and maintain your sender reputation before and during outreach. It is available as an add-on for all connected email accounts.

How it works:

• Sending volume is progressively increased over a 30-day warm-up period through real replies and positive engagement signals
• Warm-up progress — including interactions, open rates, reply rates, and spam placement — is tracked in your dashboard
• Once warm-up is complete, Inbox Protection automatically switches to maintenance mode to continuously protect your reputation

Recommended for:

• New email accounts that have never sent outreach
• Inactive accounts unused for 30+ days
• Accounts with deliverability issues or spam placement problems
• Anyone scaling outbound who wants ongoing reputation protection

Both features are available for users with All in one platform plans (Starter, Growth, Scale) in the Email accounts center.

Find leads faster with an improved AI Assistant and stop seeing companies you've already saved.

Improved AI Assistant

We've improved the AI Assistant in Discover to make it easier to go from a simple description to a ready-to-use lead list.

Type "sales managers at SaaS companies in Germany" and the Assistant sets the right filters, finds matching companies, and surfaces the contacts you need, no manual filter configuration required.

Here's what's improved:

• Describe your audience, skip the filters: tell the Assistant who you're looking for, or describe your own business, and it translates your words into a precise Discover search
• Go from companies to contacts: mention job titles in your search and the Assistant goes straight from company results to the people you need to reach
• Refine in one click: after every search, the Assistant analyzes your results and suggests how to improve them: narrowing a list that's too broad, expanding one that's too small, or sharpening targeting with filters like recent funding or specific job functions. Every suggestion is one click to apply.

Exclude saved companies from search results

Also new in Discover: you can now filter out companies you've already saved to Leads. When this filter is active, companies that are already part of your saved leads won't appear in your search results.

This means you only see new opportunities: no more scrolling past companies you've already found or accidentally adding duplicates to your lists.

Example searches to try

Copy any of these directly into the AI Assistant:

• When you know your target: "Sales Managers at SaaS companies in Germany"
• When you know your offer: "I am a Founder of a small engineering company helping with waste management in the United Kingdom"
• When you want similar companies: "Show me companies similar to AMC"

However you think about your audience, the Assistant meets you there.

Progressive Sending

Starting a new inbox or restarting one after a period of inactivity? Sending too many emails too fast is one of the most common reasons emails land in spam. Progressive Sending is a new native feature that takes care of this for you.

When enabled, Hunter automatically and gradually increases how many emails your inbox can send per day in Sequences, until it reaches your target daily sending limit. No manual adjustments needed.

How it works

• Set a target daily sending limit for your inbox
• Hunter starts with a small number of emails per day and increases the volume progressively
• The limit only goes up when you've hit the previous day's cap and your bounce rate stays healthy
• Once the target is reached, Progressive Sending completes automatically

Example progression (target: 50 emails/day):

• Days 1–3: 2–3 emails/day
• Days 4–7: 3–10 emails/day
• Week 2: 10–25 emails/day
• Week 3+: gradual increase until 50/day is reached

What it's not

Progressive Sending is not an email warm-up tool. It doesn't send warm-up emails, build reputation through artificial activity, or monitor inbox health. It controls volume pacing: helping you avoid the sudden spikes that trigger spam filters.

Who can use it

Progressive Sending is available on all All-in-One Outreach plans (including free) for:

• Newly connected email accounts in Sequences
• Email accounts that haven't sent via Hunter for 30+ days

Active inboxes won't see the option: it's designed specifically for the ramp-up phase.

Why we built this

New inboxes are the most vulnerable to deliverability issues. Jumping from 0 to your full daily limit on day one is risky, email providers flag sudden volume increases as potential spam. Until now, managing this meant manually adjusting your sending limit every few days.

Progressive Sending removes that manual work and gives every new inbox a safer start.
