How to warm up accounts so they can send more messages and don't get banned

What matters for a broadcast

• Which account is broadcasting (how long ago it was registered, what activity it normally has).
• What message you are sending.
• Who you are sending to.
• How recipients react — how often they hit spam.

Freshly registered accounts can get banned very quickly if you broadcast from them (even 5–20 messages). The more WhatsApp trusts the account, the more messages it can send before a ban.

WhatsApp's trust depends on the account's age and on whether it performs any usual actions: appearing online, conversations (preferably with your own contacts so you're in each other's address book), calls, joining groups and chatting in them, setting statuses, and so on.

Reasons for bans during warm-up

• Because of the specific numbers used to register accounts, and registration quality in general.

WhatsApp may have an initial suspicion about the account, or it may just be a delayed ban — instead of banning the registration immediately, it does so after an hour/day. The causes of poor-quality registration can be the specific numbers from the service, the proxy, the device data at the moment of registration, and so on. The same applies to accounts that get banned right after one message.

• From freshly registered accounts chatting with other new accounts.

Not always, but more often than not it leads to a ban. If one of the accounts is already under a filter (see above), all the accounts that interacted may be blocked.

• Proxies — all accounts chatting on the same IP.

Not super critical, but still worth taking into account.

How NOT to warm up accounts

Don't:

• Pair a fresh account with another fresh account in chat.
• Do many activities right after registration — heavy chatting, joining lots of groups, making many calls, and so on.
• Keep all accounts on a single IP. Even if all emulators share one IP at a given moment, you should rotate it every 5–20 minutes during warm-up, or every 5–10 accounts.

Approaches to warming up accounts

• Chat between fresh accounts and warmed-up accounts: 3–10 messages in a dialogue, every 3–8 hours.
• Appear online for 1–3 minutes. It's worth trying to stay online both with WhatsApp open and minimized (the app keeps running).
• Open unread dialogues, make random clicks.
• Join 1–3 groups every 1–2 days, post messages there (it's fine if it's just on joining).
• Calls of 20–40 seconds, 1–2 times per day. Calls to numbers should be done carefully because the people receiving them may hit spam, which leads to an account ban.
• Set up so that other people message your accounts and reply to those messages (autoresponder or manually).

You can combine all approaches and vary the overall warm-up time. You can warm up for a day, a week, or a month. Currently the best place to start warm-up is appearing online: for 1–3 days just appear online for a couple of minutes. Then try chats. Then a broadcast. UniMessenger has the functionality for all of this.

Example: Stay online for 3 minutes, 2 times a day, for 1 day → chats with warmed-up accounts, 4–6 messages, 2 days → stay online for 2 minutes, 1 day → try a broadcast (/autoresponder, group broadcasts, and so on).

You need to find an approach where the resulting message cost / number of messages per account suits you. Maybe a day of warm-up is enough and you can immediately broadcast to the bone. Or warm up for 5 days, then try broadcasting to the bone. Or you want to warm up and then broadcast 10–20–50 messages per account per day so it doesn't get banned. You should always validate approaches at volume — not on 1 account but on a group (at least 10 accounts, better 50–100), because the result on 1 account is not always what you'll get if you do the same with 1,000 accounts.

Warm-up gives no 100% guarantee — that is, even if you warm up an account for a week with daily chats, online appearances, etc., there's no guarantee it will be able to send many messages.
