First Sales Review

First Sales (firstsales.io) bundles lead sourcing, AI-written outreach, and deliverability protection into one credit-metered subscription. It positions itself less as an inbox tool and more as a full AI sales development rep: it scrapes leads, drafts and sends emails, follows up automatically, and books meetings, while warmup and list cleaning run in the background to protect the sending domain. This review covers what's verifiable from the vendor's own site, what the real per-email math works out to, and where the evidence runs thin.

Verdict at a glance

What kind of tool is First Sales?

First Sales describes itself as an AI SDR rather than a sequencer or a warmup add-on. The core loop is: find leads by scraping public sources, write and personalize an email per prospect with AI, send it, chase replies with automated follow-ups, and hand off booked meetings to a calendar. Underneath that loop sits a deliverability layer — a 21-day warmup process, pre-send list cleaning that strips invalid addresses and spam traps, and a monitoring dashboard tracking inbox placement and bounce rate. The company, founded in 2024 by Udit Goenka and described as bootstrapped, frames deliverability as the actual product rather than a bolt-on feature — a reasonable claim to make, though one that's still hard to verify independently at this stage.

How it works

Account setup is advertised at around 8 minutes, after which the platform connects mailboxes (Gmail, Outlook, or other providers) and starts warmup automatically. Every plan includes unlimited mailboxes and team seats — the real constraint is the monthly credit pool, since every action (finding a lead, writing an email, sending it, running research) consumes credits at a fixed rate rather than billing per inbox.

First Sales pricing (2026)

Credits price out at 1 credit = $0.01 pay-as-you-go, but every plan bundles credits below that rate — the discount widens from roughly 27% off on Starter to more than 70% off on Business, so effective cost per action drops sharply on higher tiers. Usage adds up fast: a standard AI-written email costs 2 credits, a premium AI email 8 credits, finding one lead 15 credits, and deep-enriching a lead 35 credits. On Starter, sending nothing but standard AI emails caps out around 2,000 sends a month before credits run out — well below the volume a per-seat sequencer would allow. List cleaning is cheap at 0.2 credits per contact. A $1-for-3-days trial converts to the monthly rate after; annual billing is advertised at up to 20% off, though exact per-plan annual prices aren't published.

What we could and couldn't verify

We could verify pricing, credit costs, and feature claims directly from the vendor's own site. We could not verify the advertised 87% inbox-placement rate or the claimed sub-2% bounce rate against any independent source — G2 and Trustpilot pages for the product returned no accessible review data at the time of writing, and no substantive Reddit discussion turned up in search. That's not unusual for a company founded in 2024 with a smaller footprint than incumbents like Instantly or Smartlead, but the deliverability numbers should be read as vendor claims, not confirmed results, until a real third-party review base exists.

Pros and cons

Pros

• All-in-one flow: lead finding, AI email writing, sending, follow-up, and meeting booking in a single subscription
• Warmup, list cleaning, and monitoring are bundled into every plan rather than sold as add-ons
• Transparent, itemized credit pricing makes the true cost of any action easy to calculate
• Effective cost per credit drops substantially on higher tiers, rewarding scale
• Fast advertised setup and a low-cost, short trial to test the workflow

Cons

• No independent review data (G2, Trustpilot, Reddit) currently exists to check vendor deliverability claims against
• Credit pool, not mailbox count, is the real usage ceiling — heavy senders can burn through Starter or Growth credits quickly
• A newer company (2024) with a shorter public track record than established cold email platforms
• Full CRM and sequencer integration details aren't clearly published; verify compatibility with your existing stack before switching

First Sales alternatives

• Slicey — managed, done-for-you Google and Microsoft inboxes (Microsoft from $0.49 per inbox) with a self-serve dashboard, delivered pre-warmed with deliverability monitoring and automatic domain swaps. Slicey customers also get Outfalcon, a free bundled sequencer with unlimited sending.
• Instantly — established cold email sequencer with its own warmup and a large mailbox marketplace; better third-party track record, less of an AI-SDR lead-finding layer.
• Smartlead — sequencing and deliverability platform popular with agencies running high mailbox volume; pricing scales by active leads and inboxes rather than credits.
• Apollo.io — combines a large contact database with sequencing, closer to First Sales's all-in-one pitch but with a much bigger, longer-established user base.
• Lemlist — sequencer with warmup and personalization tooling, positioned more for outbound teams that already have their own lead lists.
• Artisan — another AI SDR positioned around autonomous outbound, a more direct competitor to First Sales's lead-to-meeting framing than the inbox-focused tools above.

Who should use First Sales — and who shouldn't

Good fit: small sales teams or founders who want lead sourcing, email writing, sending, and deliverability handled by one tool without hiring a specialist; teams who've been burned by spam placement elsewhere and want warmup and monitoring included by default rather than upsold.

Poor fit: teams that already have a lead database and sequencer they like and just need inbox infrastructure (a dedicated mailbox provider will likely be cheaper per send); high-volume senders who will burn through credit pools quickly on the lower tiers; anyone who needs a proven, independently reviewed deliverability track record before committing budget.
