Kilomails vs Apollo

Apollo is a jack of all trades, master of none. If high-deliverability sales email is your focus, you need a specialist.

Apollo's email delivery weaknesses

  • Shared infrastructure hurts deliverability
  • Feature bloat creates confusion
  • Basic warmup capabilities
  • No smart inbox rotation
  • Complex UI slows you down

Specialist beats generalist

Apollo tries to be your prospecting tool, CRM, dialer, and email platform. We do one thing exceptionally well.

Specialized vs Generalized

Apollo tries to be everything - prospecting, CRM, calling, and email. We focus exclusively on sales email communication, which means every feature is optimized for deliverability and conversions.

Deliverability First

Apollo's shared sending infrastructure leads to deliverability issues. Our dedicated infrastructure and deliverability guard keeps you in the primary inbox.

Quality Over Quantity

Apollo's massive database sounds impressive, but data quality issues are common. We integrate with best-in-class data providers so you get accurate contacts.

Speed to Value

Apollo's feature bloat means weeks of onboarding. Kilomails gets you sending quality campaigns in under an hour.
