Who is Warmline for

Salespersons

Personalizing emails day in and out? With Warmlines, personalizing emails becomes less of a pain point. Your first line is personal and doesn't read like a template.

Founders

Reaching out to investors or customers and being told there was no "connection" is what Warmline tries to fix. Your opener is researched and intentional.

Job seekers

Networking emails? Especially on LinkedIn? Yes, I hate those too. With Warmline, you can start conversations without sounding desperate or generic.

Freelancers

As a freelancer, and builder, my cold pitches have cost me some prospects. Warmline gives you an opening that shows you have genuine interest in clients and stops them in their tracks to read your proposal.

Recruiters

Recruiters are now complaining about AI generated outreaches, a problem they created. Make your first contact with recruiters more impressive.

Agencies

Taking forever to personalize cold outreaches? Why not use Warmline, upload the detail(s) about the company, and speed up prospecting without copy/pasting templates.

Creators

If brands are not responding to your email, maybe it's because partnership emails all look the same. Create more human-tone openers that reference the creator, company or brand.

Some of our warmlines...

... warm, direct, technical, executive.

Warm

"A big congratulations on your launch, and launch thread Friday. I was interested in the pricing-by-outcome section and the comments were interesting. I'd like to know what you think is a good baseline for new product owners as I'm building one myself."

Direct

"I looked at your most recent dashboard and it throws an error on load. I can walk you through the fix in 15-20 minutes, or show you which extensions handle it if you would rather build it yourself."

Technical

"I read your piece on intercoder drift, and the same reliability gaps came up in my last annotation project. I'd like to know whether you are fixing it with a shared rubric or re-scoping the guidelines per batch."

Executive

"I saw some of your Q3 numbers, and I believe I can halve your reporting time and expenses. Worth a short call this week?"

See the difference in one line

Same prospect, same detail, different feelings.

Generic AI

"I hope this email finds you well! I came across your company and wanted to reach out because I think we could really leverage some "scalable" synergies together."

"I read your article on ghost subscribers, and it has been living in my head. The part about counting people who don't exist or will not acknowledge your posts, I refer to them as 'polite strangers', and I know how we can make them "polite friendlies"."

opened and replied to.

Made for the people the big tools ignore

No sales team, no $99/mo budget. It's you and a list of people you want to reach out to.

Freelancers

No cringe-pitch

Turn your Upwork proposal or email pitch into a warmline that shows you read their job posting or researched their company, and not just another template from ten others.

Job-seekers

The warmer the outreach, the faster the replies

Reaching a hiring manager or a founder? Lead with something interesting or specific about them, and not the generic messages.

Writers

Collabs, shoutouts, guest spots

Newsletter outreaches can be lost from the first line. Write and sound like a person who writes and reads about other people.

Tell me if the Warmline(s) landed

got it, thank you. I read these before they go up.

Don't overthink it.
Just send it.

How many times have you rewritten or "reprompted" that first line? Write in the organization's detail, take the warmline, hit send. The person on the other end will never know the agony.

Frequently Asked Questions

Is Warmline free?

Yes. Transparency: You have fifteen (15) open lines (Warmline) per browser, no credit card or signup. The paid tier (unlimited plus CSV import) is optional and comes later.

How is this different from Lemlist or Instantly?

Those are full outbound platforms at $30 to $99/mo. Warmline gives you the opening line in a human voice. Think of it as meeting a CEO for the first time: what will you say and how will you say it? That's what Warmline is for.

Does it store my prospects?

No. Nothing you type is stored on our servers. The Warmline(s) are generated and handed straight back to you.

What makes the opening lines from Warmline different from AI opening lines?

Warmline runs on Claude, but the writing rules came from a human. They were built out of real edits, line by line, on outputs that were not good enough. There is a hard list of banned phrases, quality rules, and a check that reads the opener back against your detail to catch anything it made up.
