Meta closely monitors what happens on a WhatsApp Business account, especially in its first weeks. Two signals govern how a brand is rated: account quality and sending tiers. They are closely linked, and Simio surfaces both on the home page so you can keep an eye on them.

​
Account quality

Every WhatsApp account has a quality rating that reflects how contacts have interacted with it.
A new account starts at High. After a few sent messages, contacts have engaged positively and the account has no warning attached.
Quality can drop to Medium if some contacts report the account. There is no explicit warning, but the account is on watch and you should be careful with subsequent sends.
Quality drops to Low when many contacts have reported the account. Meta flags the account and warns you; if the pattern continues, Meta may suspend the account. You should stop and review your communication strategy immediately.

​
Flagging

An account is flagged as soon as its quality drops to Low.
  • If quality improves back to Medium or High, flagging is removed automatically.
  • If quality stays at Low, flagging is eventually removed anyway, but the account is downgraded to a lower sending tier.
  • If you keep sending on a flagged account without changing behavior, Meta may suspend the account entirely. A suspended WhatsApp Business account cannot be recovered; you have to create a new one.
Simio sends an automatic email alert whenever the quality of your WhatsApp account changes.

​
Where to check quality

  • In Simio: home page (click the Simio logo top-left to reach it). Quality is shown next to the connected WhatsApp number.
  • In Meta Business Manager: WhatsApp Manager for your account.
If activity settles and no more contacts report the account, quality can recover from Low to Medium, and sometimes back to High.

​
Sending tiers

New WhatsApp accounts have to prove they are legitimate before Meta lifts their daily volume ceiling. Sending tiers cap how many conversations you can start in a rolling 24-hour window. A new account starts at Basic while Meta verifies it (usually within 24 hours), then moves to Tier 1. Meta may promote directly to Tier 2 if it recognizes the brand’s reputation (via the company website provided at account creation). A phone number that was already used on WhatsApp Business may resume at its previous tier.

​
How to move up a tier

Three conditions must all be met:
1

Maintain High or Medium quality

See the section above.
2

Start at least 50% of the tier's cap over 7 consecutive days

On Tier 1 (cap 1,000), that means starting at least 500 conversations in a 7-day window.
3

Wait 24 hours after crossing the threshold

Meta applies the tier upgrade after a short delay.

​
Where to check the tier

  • In Simio: home page, next to the account quality.
  • In Meta Business Manager: same page as account quality. Meta also shows the current tier’s upgrade conditions and whether each is met.

​
What happens if you exceed the tier limit

Once you hit the cap in a 24-hour window, Simio stops the campaign in-flight. Any queued messages are shown as Spam Rate limit hit errors in the delivery log. The account is then restricted for 24 hours (no new outbound conversations allowed) before you can send again.

​
Warming up a new account

To move up tiers safely without triggering flagging, warm up the account with these practices:
  • Send your first campaign to your most engaged customers. High engagement on the first sends signals Meta that this is a trusted account.
  • Target a small, opted-in segment. For example, loyal customers you announce the new WhatsApp channel to.
  • Include an unsubscribe button in the message, linked to an opt-out step in the flow. Contacts who don’t want to be reached can opt out, which is far better than being reported as spam.
  • Launch conversational automations (like abandoned cart, order confirmation) alongside campaigns. Contacts replying to those automations increase account trust.
Do not send to your entire opted-in base on day one, and do not send campaigns without an unsubscribe button. Both are the fastest ways to get flagged.
Spread the first campaign over several days, doubling the daily volume as long as quality stays green: At that pace, a 3,000-contact base is fully activated in 3 days, a 10,000-contact base in 5 days. Start by isolating a segment of highly engaged customers, for example:
  • Has a phone number.
  • Is opted in to email.
  • Has made at least 2 purchases this year.
Then split that segment by purchase count, sending to the most engaged first:
If Meta issues a warning at any point during the ramp-up, cancel the pending sends and reach out to Simio support to adjust the strategy.
