⚠️ Important reality check

“Unlimited emails” sounds great, but there’s a catch:

• Email providers (Gmail, Outlook) limit deliverability, not your tool

• Sudden high-volume sends can land you in spam

• You still need warm-up, domain reputation, and list quality

Even Reddit users warn:

“Unlimited daily sending is usually a terrible idea for deliverability.” Reddit
