You need to send cold email from 15 different email accounts. Which tool is more cost-effective?

🎉

Correct! Instantly gives you unlimited email accounts at $30/mo. QuickMail Basic only allows 5 accounts, so you'd need the Pro plan ($89/mo) for 15+ accounts.

💡

Instantly ($30/mo) includes unlimited accounts. QuickMail's Basic plan caps at 5 accounts — for 15 accounts, you'd need Pro ($89/mo), which is 3x the price of Instantly.

Who should choose QuickMail?

  • Teams where deliverability is the number one priority
  • Agencies managing multiple client campaigns who want a clean, focused interface
  • Teams with existing lead lists who just need reliable, high-quality sending
  • Users who prefer a simpler, less cluttered interface

Who should choose Instantly?

  • Budget-conscious teams wanting the lowest price for cold email
  • High-volume senders who need unlimited email accounts
  • Teams that want a B2B lead database alongside their sending tool
  • Anyone who wants the most features per dollar
Test yourself

You're choosing between QuickMail and Instantly. Deliverability is your top concern, and you only use 3 sending accounts. Which should you pick?

🎉

Right! If deliverability is your top priority and you only need a few accounts, QuickMail's focused approach and AutoWarmer give you the edge. Instantly's unlimited accounts advantage doesn't matter if you only use 3.

💡

QuickMail's core strength is deliverability. With only 3 accounts, you don't need Instantly's unlimited accounts, and QuickMail's AutoWarmer and deliverability monitoring are more focused.
