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.

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.
