Swift Pilot, built in
Paid plans include monthly credit: $5 on Starter, $10 on Growth and $30 on Agency. Charged by usage. Top up any time from $10; bought credit never expires.
Research, writing, approval, sending and replies in one app. Here is what each part does, and which plans include it.
Drop in the spreadsheet you already have. The app reads it, suggests which column is the email, name, company and website, and you confirm before anything is imported.

The Email verifier checks the format and the domain, screens for throwaway providers, shared inboxes and typing mistakes, then asks the receiving mail server whether the mailbox exists.

You describe your offer and your voice once per campaign. For every lead the AI reads their website, keeps the facts a sharp rep would mention, and writes around them.

Connect OpenAI, Anthropic, Gemini, OpenRouter or any compatible API. It costs no Swift Pilot credit, and Swift Pilot stands behind it as a backup if your key fails.
Put connections in priority order. When one is rate limited or down, the next takes over. Keys are encrypted and never shown again.

A campaign is five short steps: choose leads, subject, message, sending rules and review. Preview real emails while you set it up.

Connect every account you send from. Volume spreads across them so no single mailbox gets hammered.

Connect each mailbox that receives replies. They are checked on a schedule, each reply is matched to its lead and campaign, and you answer through the right account.

The details that matter once you run outreach every week.
Per-campaign reporting. Replies are tracked on every plan; open and click tracking is on Growth and Agency.
A one-click unsubscribe header and link in every email. Opt-outs go on a suppression list you can always check.
Keep brands or clients apart, each with its own mailboxes, leads and AI settings. 1 on Starter, 3 on Growth and 25 on Agency.
Invite teammates to the workspaces they work on. 1 on Starter, 3 on Growth and 10 on Agency.
Mailbox passwords and AI keys are encrypted at rest, never shown again after saving and never written to logs.
Open a ticket where you work. Free plan: replies within 24 hours on business days. Paid plans: VIP priority, usually within an hour.
Start on the Free plan: connect a mailbox, upload a list and read the emails Swift Pilot writes before anything is sent.
