How to Book 50 Sales Calls with Cold Emails

GUIDES
Blog > Guides> Guide for beginners

Step 1: Get 10,000 email contacts

Use tools like Apollo.io and Explee.io to find your audience and export emails. Apply filters for location, job title, company size, and industry.
Validate your data using services like Leadmagic.io or Listkit.io

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 warmup (80/day per mailbox, ramp-up disabled) and keep it running permanently — including after your campaigns go live.
  • After 14 days of warm-up, start sending a maximum of 15 cold emails per day per mailbox, including follow-ups.

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.

Learn more about copy in our copywriting guide.

Below are examples of email templates

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 your campaigns in Instantly or PlusVibe. If you use Smartlead as your sequencer, never enable its warm-up.
  • Process inbound leads: answer questions and invite them to a call.
Most cold emails fail simply because they land in spam. People never even see your offer. Our SMTP and Google Workspace mailboxes are built specifically for outbound; this means your emails will finally be seen, and you’ll start getting more positive replies.
