Why SaaS teams switch
Outbound that sells software, not spam
SaaS buyers are flooded with cold email. The ones that get replies land in the inbox, speak to a real problem, and follow up. FirstSales does all three automatically.
Lands in the primary inbox
21-day AI warm-up, free list cleaning, and SPF/DKIM/DMARC done right push you to 87% inbox placement — so your pipeline isn't capped by the spam folder.
Speaks your product
The AI writes from a knowledge base of your features, ICP, and positioning, so every email reads like your best AE wrote it — at the volume of a whole team.
Books demos on autopilot
It follows up until the prospect replies or books, then routes the reply to you. You wake up to a calendar ofqualified demos.
How it works for SaaS
From cold list to booked demo in three steps
Point FirstSales at your ICP and let the AI run the outbound motion your SaaS team never has time for.
Connect your mailboxes and warm up
Plug in your sending accounts and let the 21-day AI warm-up build sender reputation with real conversations before a single prospect is touched.
Unlimited Google and SMTP/IMAP mailboxes Add as many sending accounts as your SaaS team needs, no per-seat cap.
21-day automated reputation warm-up Builds inbox trust via real conversations before any prospect is touched.
Guided SPF, DKIM, and DMARC setup Step-by-step authentication setup catches every misconfiguration before sending.

Feed the AI your product knowledge
Drop in your positioning, features, ICP, and proof points. The AI uses your knowledge base to write personalized outreach that sounds like your team — not a template.

What you get
Everything a SaaS team needs to run cold email that converts
Deliverability, AI writing, and automation in one platform — so you don't stitch together a verifier, a warm-up tool, and a sequencer just to get a reply.
Land in the inbox, not promotions
Warm-up, free cleaning, authentication, and live monitoring protect every domain so your SaaS outbound stays in the primary inbox at scale.
21-day smart warm-up Ramps sending volume gradually so inbox providers trust your domain early.
Free automated list cleaning Removes invalid and risky addresses before they hurt your sender score.
Real-time inbox monitoring Alerts you the moment a domain drifts toward promotions or spam.

Personalization that sounds human
The AI researches each prospect and writes from your knowledge base, so a 5,000-contact campaign reads like 5,000 one-to-one emails.
Knowledge-base-grounded copy Every email draws on your actual features and differentiators, not generic filler.
Per-prospect personalization Role, company size, and tech stack shape the message each contact receives.
Your voice, your positioning Tone mirrors your best AE, not a default AI cadence.

Follow-up that never forgets
Multi-step sequences with smart stop-on-reply mean every prospect gets the follow-ups that actually book demos — without your team lifting a finger.
Autonomous follow-up sequences Each prospect moves through timed steps without a rep scheduling the next touch.
Smart stop-on-reply Sequence halts the moment a prospect responds, so no double-sends after interest.
Books demos around the clock Follow-up runs nights and weekends, catching prospects outside your team's hours.

Before & after
What changes when SaaS outbound runs itself
The old way burns domains and reps. The FirstSales way fills the pipeline while your team focuses on product and closing.
- Emails land in spam
- Cold sends hit promotions or spam and your pipeline is capped before it starts.
- Generic templates
- Mass blasts ignore the prospect's product and stack, so reply rates flatline.
- Follow-ups slip
- Busy reps forget to follow up, and most of the pipeline dies in the gap.
- Burned domains
- Aggressive sending without warm-up torches sender reputation and your domain.
- Stitched-together tools
- A verifier here, a warm-up tool there, a sequencer somewhere else — and a bill to match.
- Expensive SDRs
- A human SDR costs $5k+/mo with a 3-month ramp before a single booked demo.
- 87% inbox placement
- Warm-up, cleaning, and authentication keep you in the primary inbox at scale.
- AI-personalized at scale
- Every email is written from your knowledge base to the specific prospect.
- Autonomous follow-up
- The AI follows up until a reply or a booked demo — nothing slips.
- Protected reputation
- Smart throttling and live monitoring keep every domain healthy.
- One platform
- Deliverability, AI, and automation in a single tool from $29/mo.
- No ramp, no salary
- Launch in 8 minutes and run an SDR's motion for a fraction of the cost.
