Tools 12 found in our last check

  • scan_domain

    Read a product's website and return its ideal customer profile, a first cold email and the best-fit companies scored 1-10. Takes about 30 seconds.

  • import_leads

    Clean your own list (CSV text with an email column, optional company, name, website) into leads: drops invalid, duplicate, already-emailed, public-sector, role-mailbox (info@, support@) and no-mail-server addresses, and says why. A list that is mostly unmailable is refused whole…

  • get_email_allowance

    How many outreach emails are left this month on the plan.

  • export_outreach

    Everyone this account has emailed, as CSV: email, company, contact, product, subject, delivery, replied, reply category.

  • list_sending_domains

    The account's sending domains and managed GrowFast address, with remaining sends today.

  • list_autopilots

    Every autopilot on the account (one per product) with its last result.

  • set_autopilot

    Create or change the autopilot for one product and turn it on or off. Each day it finds new fits (8/10 or better), writes to the decision-maker and sends real email within the daily limit; sent email cannot be recalled.

  • send_reply

    Send the founder's answer to a prospect who replied, in the same thread, from the address they wrote to. Delivers real email that cannot be recalled.

  • list_reddit_monitors

    The Reddit monitors on the account, one per product.

  • set_reddit_monitor

    Set what to listen for on Reddit for one product. Replaces that product's existing monitor settings. GrowFast finds posts where the author needs the product and drafts a reply and DM; the founder posts them.

  • list_reddit_matches

    Reddit posts found for a product, best first, with drafted replies.

  • draft_outreach_emails

    For up to 10 companies find the named decision-maker on each company's own site and write a first email to them. Nothing is sent and nothing is saved: the founder reads and edits the drafts. Takes 10-60 seconds.
