Boom — your lead list is ready!
Step 2: Set up mailboxes
  • Sign up to maildoso.ai.
  • Create 30 SMTP mailboxes for $75 and register 5 domains for $60 in minutes.
  • Connect mailboxes to Instantly or another sequencer.
  • Launch 14-day warm-up.

No tech headaches — just fast and easy setup!
Step 3: Prepare your copy
Create 5 different copies.
Template structure:
  1. The problem they face.
  2. What your company does.
  3. Case study/result of your other client.
  4. CTA: Offer to show them a demo video/lead magnet.

Step 4: Create a lead magnet
Option 1 – A video (the best option)
  • Use Loom to record a 2-5 minute video.
  • Get to the point fast and show the problem you solve.
  • Add scarcity/urgency (exclusive discount code).
  • End with a clear call to action to sign up/book a call.

Option 2 – A case study / guide / freebie
Send something that brings more value to the prospect.
  • A nicely structured case study of your other client.
  • A guide explaining how your tool solves a problem.
  • A free trial/audit.
Step 5: A campaign launch and inbox management
  • Launch campaigns in Instantly.io or Smartlead.ai.
  • Process inbound leads: answer questions and invite them to a call.
