Why ReachStack

Cold outreach is broken. Not because of email — because of templates.

The fix isn't more sends, more sequences, or more "warm-up". It's better research. ReachStack does the research a senior SDR would do — every contact, every send.

Templated outreach

“Hi {first_name} — quick question.”Same opener to 800 prospects. Reply rate: 0.4%.
Personalization tokens.Variable insertion is not personalization. Buyers can smell a mail-merge.
Research, but only on big accounts.Your top-50 list gets love. The rest get the template.
Volume to make up for low reply rate.More sends → more burn → more blocked domains.

ReachStack

Researched openers, every time.Real context — funding, recent post, product launch. Reply rates 2–4×.
Per-contact AI composition.The body changes by contact, not by token. Review queue keeps you in control.
Research scales linearly.Same depth on contact #800 as on contact #1. No tiering.
Quality over quantity.Send fewer, land more. Better deliverability as a side effect.

FAQ

Questions, answered.

How is ReachStack different from Outreach.io or Lemlist?

ReachStack does the research for you. Outreach and Lemlist are sequencing tools — you bring the data and write the copy. ReachStack pulls company news, LinkedIn activity, tech stack and funding signals automatically, then writes the email body using those signals. You review and approve before send.

Where does the AI research data come from?

Can I review emails before they send?

How do you handle deliverability?

What email providers do you connect?

Can multiple people on my team use it?
