It turns a lead list into personal cold emails. For each lead it reads their website, writes a one-to-one email around what it found, waits for your approval, sends it from your mailboxes in rotation, and collects replies in one inbox.

A mailbox to send from (SMTP), a mailbox that receives replies (IMAP, often the same one), and a CSV of leads with at least an email address. A website column makes the research much better. Paid plans include Swift Pilot, so a key of your own is optional; the Free plan needs your own AI key.

Connect a mailbox, upload a list and create a campaign; the first emails are written while you watch. A checklist on the dashboard shows what is left.

Yes. Each one is written for that lead from what the AI found on their website and the fields in your list. You set the offer, tone and length once per campaign.

Yes. Campaigns start in review mode: every email waits in a queue where you approve, edit or ask for a rewrite. You can switch a campaign to automatic sending once you trust it.

OpenAI, Anthropic, Google Gemini, OpenRouter, and any OpenAI-compatible API. Add several and set their order; if one is rate limited or down, writing moves to the next one.

Paid plans include Swift Pilot, so you can start without your own key. It writes up to 100 emails a day on Starter, 300 on Growth and 1,000 on Agency, from the page each lead's website link opens. Connect your own AI key to research several pages of a site and to remove the daily AI limit. The Free plan uses your own AI key.

Each email goes from the healthy mailbox with the most room left today, within its daily and hourly caps and minimum gap. Volume spreads evenly, and a lead keeps hearing from the same mailbox.

If the login is rejected, the mailbox is marked as needing attention, you get a notice, and it is skipped until you fix it. After five failures in a row it is switched off automatically.

Start new mailboxes with low daily caps and raise them gradually. Use a domain separate from your main business domain for cold outreach.

It checks a lead list in bulk before you send. For each address it checks the format, whether the domain exists and can receive email, and known lists of throwaway providers, shared inboxes such as info@ and typing mistakes such as gmial.com. Each lead is marked Valid, Risky, Invalid or Unknown. It does not connect to mail servers, so it cannot confirm that one particular inbox exists, and it does not detect catch-all domains. It is included on every paid plan, with a monthly allowance equal to the plan's lead limit (Starter up to 2,000 leads a month, Growth up to 25,000, Agency up to 100,000). It is not included on the Free plan.

Spam. You may only email people with a genuine, relevant business reason, honour every opt-out, and follow the laws where you and your recipients are. Accounts that break the acceptable use policy are suspended.
