Client wants 500 emails a day from 5 inboxes. How do I explain this is insane

New agency client wants 500 cold emails per day from only 5 inboxes. That is 100 emails per inbox per day. I tried explaining this will get everything burned but they insist their last agency did this.
Here is how I explained it: Google Workspace has a daily sending limit of 2,000 per account, but that does not mean you should send 2,000 cold emails. Google monitors sending patterns. More than 20-30 cold emails per inbox per day dramatically increases your risk of suspension and spam placement.
To send 500 emails per day safely, you need 25-30 inboxes at 20 emails per inbox. That is the math. Trying to shortcut with fewer inboxes will result in burned domains, suspended accounts, and wasted money.
I gave them two options: 1. Get 30 PuzzleInbox inboxes and send 500/day safely. 2. Keep 5 inboxes and send 100/day total. They went with option 1. Sometimes clients just need to see the math.

100 emails per inbox per day lmaooo that's how you get suspended in 48 hours. their "last agency" probably got fired for burning all their domains

the safe limit is 15-20 per inbox per day. that's not a suggestion, that's what Google and Outlook will tolerate without flagging you. 100 per inbox is suicide

We see this constantly. Clients confuse Google's 2,000/day technical limit with what's safe for cold email. The technical limit exists for legitimate business email, not cold outreach. 15-20 cold emails per inbox per day is the real ceiling.

the math explanation is the best approach. show them: 500/day divided by 20 per inbox = 25 inboxes needed. at $3-4.50/inbox that's like $100/month. there's literally no reason to overload 5 inboxes when spreading it out is this cheap

I put it in the contract now. maximum 20 sends per inbox per day, no exceptions. if a client pushes back they're not the right client for me

glad they went with option 1. 30 inboxes is the right call. pro tip: use 3 inboxes per domain so you need about 10 domains for 30 inboxes. separate domains from your primary business domain obviously

educating clients on safe sending limits is literally 50% of agency work. the other 50% is actually running the campaigns lol

had a client like this once. refused to listen. burned through 15 domains in 2 weeks. came back asking me to fix it. some people have to learn the hard way
