Swift Outbox vs Instantly, Smartlead and lemlist

All four send cold email. Here is what we do differently, the public entry prices, and the questions worth asking any vendor, answered for us.

What is different here

Research comes before writing

Every email starts from the lead's own website, not from a template with merge fields. The result reads like you looked, because the AI did.

You approve what goes out

A review queue sits between writing and sending. Approve, edit or rewrite, then switch a campaign to automatic once it has earned it.

Verification is part of the plan

Paid plans include the Email verifier, with a monthly allowance, so you do not need a separate list-cleaning tool.

AI included, keys optional

Swift Pilot writes from credit included with paid plans. Bring your own key instead and it costs nothing extra.

Entry prices, billed monthly

Check before relying on these. Competitor prices are list prices for each vendor's cheapest email plan, billed monthly, as shown on their public pricing pages (October 15, 2026). Vendors change pricing often and limits differ between plans, so follow the links for current details.

Questions to ask any cold email tool

Put these to every vendor you try. Here are our answers.

Does it research each lead before writing?

Yes. The AI reads the lead's website and writes around what it finds, on every plan.

Can I check every email before it sends?

Yes. Emails can wait in a review queue. Automatic sending is an optional setting per campaign.

How is volume spread across mailboxes?

Each email goes from the healthy mailbox with the most room left today, inside per-mailbox daily and hourly caps. A lead always hears from the same mailbox.

What happens when an AI provider rate-limits?

Writing moves to your next AI connection immediately, in the priority order you set.

Can I check my lead list before sending?

Yes, on paid plans. The Email verifier marks each address Valid, Risky, Invalid or Unknown by checking the format, the domain and the receiving mail server, and it flags catch-all domains. Yahoo and AOL do not confirm mailboxes, so those show as Risky.

Where do replies go?

All connected reply inboxes feed one shared inbox, matched to the right lead and campaign.

Do I pay per seat?

No. Plans are priced as a bundle. Starter includes 1 seat; higher plans include more.

Do I need a separate AI subscription?

No. Paid plans include Swift Pilot credit ($5 a month on Starter). Your own OpenAI, Anthropic, Gemini or OpenRouter key also works, at no Swift Pilot cost.

Is it the right tool for you?

An honest answer saves us both time.

A good fit if you

  • Want every email written for one lead, not merged from a template
  • Want to read emails before they go out
  • Send from several mailboxes on your own domains
  • Already have lead lists, or buy them elsewhere

Look elsewhere if you need

  • A built-in database of contacts to buy
  • Mailbox warm-up inside the same tool
  • LinkedIn or phone steps alongside email

See the difference on your own leads.
