ScalarSignal researches each lead, finds what you genuinely have in common, and writes a one-to-one email that reads like it came from someone who knows them. No templates. No links. No prices.
No credit card required · 7-day free trial on paid plans
You research. You write. You send. Then nothing. Because most cold email feels like a template, not a human.
"Hi [Name],
I'm a [title] at [company]. I noticed your [thing] and thought it'd be great to connect.
Can we hop on a call? Here's my link: [calendly.com/generic]
Best,
[Sender]"
Five steps. Under 30 seconds. Human-sounding every time.
Whether you're selling or raising, ScalarSignal has a playbook built for you.
Scrapes professional signals (company news, funding, job postings, pain points) and writes emails that start real conversations instead of adding to the pile.
Finds common ground with angel investors using personal signals: sports teams, alma mater, hobbies, podcast appearances. Written peer to peer, never desperate.
Anyone whose next reply matters more than their next thousand sends.
ScalarSignal is a cold email tool for people who need replies, not volume. You add a lead, and ScalarSignal researches that person's public footprint, finds what's relevant to your offer and what you genuinely have in common, and drafts a short one-to-one email with no templates, links, or prices. You review it and send it from your own inbox.
Founders doing their own outreach (why nobody replies), founders emailing investors (Capital mode), agencies and consultants winning clients (agencies), and sales teams working their most important accounts (sales teams). It fits best when your list is in the dozens or hundreds and every contact matters.
Those tools are built to send at scale, run multichannel sequences, or supply contact data. ScalarSignal is built to write one email for one person, using persona matching: common ground between you and the recipient. See the comparisons with Instantly, Lemlist, and Apollo.
The 2026 industry average for cold email is 3.43 percent, and it keeps falling as sending volume rises. ScalarSignal is built to get you out of that average by making every email specific to the person reading it. We'll publish our own measured reply data once enough real sends have run through the product.
No, on purpose. ScalarSignal sends at low volume from your own connected Gmail or Outlook inbox, without tracking pixels or link shorteners. If you need to send thousands of emails a month, a volume tool is a better fit; our guide to cold email software covers the options honestly.
The Starter plan is free for 10 leads a month. Growth is $39 a month for 200 leads, and Pro is $99 a month for unlimited leads. Paid plans include a 7-day free trial.
