What is First Sales

Vendor's own claim

FirstSales is an AI SDR product whose core differentiator, per its own marketing, is a deliverability engine (warm-up, list cleaning, monitoring) layered on top of AI email generation and sending.

Ideal customer profile

Vendor's own claim

Founders and small sales teams who want an automated cold-email outbound motion without hiring an SDR, per the vendor's own cost comparison (SDR salary+commission vs. FirstSales' all-in annual cost).

Who should look elsewhere

Our read

The whole product is metered on a shared credit system across every plan (2 credits per standard AI email, up to 60 credits for premium AI research), so email volume is capped by plan tier (4,000 credits/mo on Starter) rather than truly unlimited, despite 'unlimited mailboxes' messaging. A/B testing, webhooks, and priority support are gated behind higher tiers (Growth and Pro), and teams needing phone support or a dedicated account manager must reach the $499/mo Business tier. Because the tool is centered on cold email at scale, teams whose ICP or compliance requirements disfavor cold outbound (e.g. regulated industries with strict opt-in rules) are working against the product's core workflow.

Vendor's own claim
Is there a machine-readable OpenAPI spec?

This is a gap in what we retrieved, not evidence the real spec doesn't exist elsewhere.

Our read
Is there a status page?

That is what we could not retrieve, not evidence no status page exists; confirm with the vendor.

Our read
What claim does FirstSales make about inbox placement?

The vendor claims 87% inbox placement versus a 60-70% range it attributes to competitors, and cites a Mailshake 2025 report that 1 in 5 cold emails land in spam industry-wide; these are vendor claims we have not independently verified.
