<b>Daily send limits: the number every tool lets you ignore</b>
The most common deliverability question has a boring answer: send less per inbox than you think.
Keep each warmed inbox at ~30-50 cold emails/day, even on aged domains. Google Workspace's hard cap is ~2,000/day, but cold senders who approach that get filtered fast. Want 500/day? Run 10-15 inboxes, not one hot mailbox.
Smartlead and Instantly enforce per-inbox limits and distribute campaigns across your pool automatically — the feature that makes this manageable.
Pros / Cons
— Low per-inbox volume + many inboxes: durable, costs ~$6/inbox/mo
— High volume per inbox: cheap setup, fast reputation collapse
— Auto-distribution: essential, both major tools have it
Who it's for: anyone scaling past ~50/day needs the inbox-pool math, not a hotter single mailbox.
Verdict: 5/5 — spread volume thin across many inboxes. The tools enforce this for you; the discipline is buying enough inboxes instead of pushing one too hard. Volume is an infrastructure problem, not a settings toggle.
