Safe sending
Safe sending is the set of limits Spaces keeps on every connected account: a daily cap, a gap between messages, a slower start for new accounts and a stop when a platform restricts the account. It lowers the risk of a restriction, though no tool can promise that a platform will never act.
What it does
Safe sending keeps every account inside daily limits, paces its messages and warms new accounts up slowly.
You, to your AI agent: Send the opening-night invite to everyone on the list who asked for it.
Your AI agent: I have started 10 new WhatsApp chats today, which is the daily limit for new chats on this number. I will send the rest tomorrow. Replies to customers are still going out as normal.
Why limits protect your business
WhatsApp, Instagram, LinkedIn, Messenger, X and email providers all watch for accounts that send too much, too fast, or to people who never answer. An account that looks like it is spamming can be slowed down, signed out or restricted. For a small business, losing the number customers know is a real cost.
Platforms restrict automation on personal accounts, and each one decides on its own. Spaces cannot make that risk go away, but it keeps every account inside limits that follow the published guidance for each platform, set at or below what it recommends.
What Spaces does on every account
These protections are on for every account and cannot be switched off:
- a daily limit on messages, and a tighter one on new chats with people who have not written to you
- a gap of several seconds between messages, so the account never sends in bursts
- a four-week warm-up for newly connected accounts, starting slow
- a refusal when the same cold text goes to many people
- a refusal for any message to someone who said stop
- a stop on any account the platform has restricted, until it is reconnected
What it means for your customers
The tightest limits are on new chats. Replies in a chat a customer started are not held back by the warm-up, so customers get answers from the first day.
When a message is held back, nothing is lost. Your agent waits the time Spaces gives it and tries again with the same message, so it is never sent twice.
The limits are the same for every account. You cannot raise them, and there is no setting to lower them or to give an account its own working hours. If you want to go slower, tell your agent to send less, set working hours on scheduled messages and routines, or pause sending.
How to use it with your AI agent
- Connect your accounts. In your Spaces dashboard, connect the accounts you already use. WhatsApp links with a QR code, the same way you would link WhatsApp on a computer. Instagram, LinkedIn, Messenger, X and email connect by signing in through a secure link.
- Add Spaces to your AI agent. Add Spaces to the AI agent you already use, such as Claude Code, Claude, Cursor, Codex, ChatGPT, Grok, OpenClaw and Hermes. Each one has a short setup page, and most sign in through the browser with no code to copy.
- Message people who expect you. Use Spaces for customers and contacts who know your business. That is the single biggest thing that keeps an account healthy.
- Ask how much room is left. Ask your agent how many messages and new chats an account has left today before a busy send.
Things you can say to your agent:
- “How many new chats can my WhatsApp number start today?”
- “Is any of my accounts paused or signed out?”
- “Send these invites over the next few days rather than all at once.”
- “Why was my last message held back?”

Limits that apply
- WhatsApp starts no new chats for the first 24 hours after connecting, then 3 a day in week one.
- LinkedIn connection requests: 5 an hour, 20 a day, 100 a week (5 a day in week 1).
- Instagram comments: 4 an hour, 20 a day.
- Email: 80 a day, one email at a time to one person, at least 30 seconds apart.
- X: 100 messages a day. X has no published figures, so Spaces uses conservative limits of its own.
Every channel’s limits are on sending limits, and how Spaces protects accounts is on account safety.
FAQ
Can Spaces promise my account will never be restricted?
No. Each platform decides on its own, and no tool can promise that. Spaces lowers the risk with limits, pacing and warm-up, and stops sending if an account shows signs of a restriction.
Can I raise or lower the limits?
No. The limits are the same for every account. To go slower, tell your agent to send less, set working hours on scheduled messages and routines, or pause sending.
Will limits slow down replies to my customers?
Rarely. Replies in a chat the customer started are not held back by the warm-up. The tightest limits are on new chats.
What is warm-up?
A newly connected account starts with fewer new chats a day and builds up over four weeks, the way a person using a new account would.
What happens when a message is held back?
Nothing was sent. Your agent waits the time Spaces gives it and tries again with the same message, so it never goes out twice.
What happens if a platform signs my account out?
Sending stops for that account until you reconnect it from your dashboard. Reading your other accounts keeps working.
