How many emails should a mid-size team send daily?
50-100 per rep across 5-10 warmed accounts. For a 20-rep team, that's 1,000-2,000 daily emails. Instantly handles this volume easily on the Growth plan ($97/mo).
Instantly or Lemlist for SMBs?
Instantly for volume-first outbound. Lemlist for personalization-first approaches with smaller target lists. Most SMBs doing traditional cold outbound prefer Instantly's simplicity and deliverability.
How do SMBs manage cold email compliance?
Use dedicated sending domains (not your corporate domain), include unsubscribe links, and maintain a suppression list. Instantly and Lemlist both handle opt-out management automatically.
