Why new accounts are reviewed

Email platforms send mail for thousands of businesses from shared infrastructure. If one customer spams, mailbox providers start filtering everyone. So Brevo, like its competitors, reviews new accounts before they can send campaigns. It asks who you are, what your website is, how you collected your contacts and what you plan to send.

Accounts with vague details, no website, or a freshly imported list that looks bought are held or refused. Honest, complete answers get approved faster.

People most often use one of our numbers for Brevo to:

• A one-off code during sign-up, with your real business details provided for the account review

Many apps expect the number you keep. We help with the cases above; we do not help anyone reach an account that is not theirs — see our acceptable use policy.

Where your contacts came from

Brevo requires that contacts agreed to receive your messages. Purchased lists, scraped addresses and shared lists from partners break that rule and, in the EU and many other places, data protection and anti-spam laws. They also produce high bounce and complaint rates, which trigger suspension.

Creating fresh accounts to keep sending to such lists is exactly what the review is designed to catch. We do not support using our numbers for it.

Authenticate your domain

Since 2024, Gmail and Yahoo have required bulk senders to authenticate their mail with SPF and DKIM, publish a DMARC policy, and offer one-click unsubscribe. Brevo guides you through adding the DNS records for your sending domain. Without them, campaigns increasingly land in spam or are rejected.

SMS and WhatsApp campaigns

Brevo also sends SMS and WhatsApp messages. Those channels have their own rules: sender registration in some countries, WhatsApp template approval, and strict consent requirements. Texting people who did not opt in is illegal in many places and quickly damages your sender status.

Protecting the account

A Brevo account holds customer contact data and can send messages in your brand's name. A takeover can mean a data breach and a phishing campaign sent from your domain. Turn on two-factor authentication, give colleagues their own logins with suitable permissions, and use API keys with care.

Keeping your list healthy

Even an opted-in list decays. People change jobs, abandon addresses and stop opening. Remove hard bounces straight away, suppress contacts who have not engaged in many months, and use double opt-in for new sign-ups. A smaller list of people who want your emails gets better delivery than a large list full of dead addresses, and keeps your account in good standing.

API and SMTP keys

Websites and apps send transactional emails through Brevo with API or SMTP keys. Store them in server-side configuration, never in public code or front-end scripts, and rotate them if they leak. Leaked keys are used to send spam through your account, which can get it suspended.

Phishing aimed at marketers

Marketing teams receive fake "account suspended", "payment failed" and "new sign-in" emails styled as their email platform, with links to fake login pages. Sign in to Brevo directly to check any notice, and treat unexpected requests to "re-verify" your account with suspicion.

Installing Brevo and verifying the number

When the code does not arrive

In order of how often each one is the real cause:

1. Your account is pending review
   Complete your company and website details, and explain how contacts were collected.
2. Your account was suspended
   High bounces or complaints, or a non-compliant list, are common causes. Contact Brevo.
3. Campaigns land in spam
   Authenticate your domain and clean your list.
4. Spam was sent from your account
   Rotate API and SMTP keys, reset passwords and turn on 2FA.
5. A verification code did not arrive
   Check the number and country code, then request again.

Working out which case you are in

1. Did your contacts opt in? Yes Import them. No Do not send to them.
2. Is your domain authenticated? Yes Good. No Add SPF, DKIM and DMARC.
3. Is 2FA on? Yes Good. No Turn it on.
4. Are keys in public code? Yes Rotate them. No Good.

Before you request another code

• Give accurate company details
• Use only opted-in contacts
• Authenticate your domain
• Offer easy unsubscribe
• Turn on 2FA
• Keep keys private
