SALES STACKCOLD OUTBOUND

Instantly. The cold email engine.

Instantly is the core cold email platform for Cashflow Positive AI. It handles the sending, warming, and sequencing infrastructure so the team can focus on message quality while delivery stays healthy. Cold email is a technical sport. Instantly removes the infrastructure headache so the copy can do the work.

Unlimited sending accounts

Scale outreach without putting all volume through a single mailbox. Add accounts, split sends, and keep the overall delivery profile healthy.

Built-in warming

New mailboxes do not start cold. Instantly warms accounts so inboxes build trust before high-volume campaigns begin.

Sequence + A/B testing

Write multiple variants, schedule follow-ups, and let the data decide which message wins. Iteration is the only sustainable edge in outbound.

CRM and enrichment integrations

Connect lead data, enrichment tools, and CRM records so the right message reaches the right person at the right time.

Why I recommend it

Most cold email tools either break at scale or take a full-time hire to manage. Instantly handles the volume, warming, and sequencing in one place, which means the team can spend time on the message, not the mailbox plumbing.

The standard workflow
  1. 01Upload or sync the lead list and verify the enrichment is complete.
  2. 02Split leads across warmed mailboxes with a clear daily send limit.
  3. 03Launch the first sequence with at least two message variants.
  4. 04Review reply and meeting-booked rates after 48-72 hours.
  5. 05Double down on the winning variant and kill the losers fast.
