The platform’s warmup processes make sure that our cold emails don’t bounce into spam filters. It also makes use of AI behavior tracking as we’re sending which is great for campaigns scaling. It’s also really valuable to be able to track open rates and responses.

Brevo authentication
How To Authenticate Your Brevo Sending Domain
Brevo (formerly Sendinblue) handles campaigns, automations and transactional mail. Gmail, Yahoo and Microsoft require authenticated email from bulk senders, so a authenticated sender domain with valid SPF, DKIM and DMARC is the baseline for reaching the inbox.
- 01Open Brevo with an account that has administrator access.
- 02Go to Senders, Domains & Dedicated IPs → Domains.
- 03Add the sending subdomain you want to use, for example send.example.com.
- 04Copy the DNS records Brevo generates - typically DKIM TXT and CNAME records generated by Brevo.
- 05Publish each record with your DNS provider, exactly as shown.
- 06Return to Brevo and run verification once DNS has propagated.
- 07Publish a DMARC TXT record at _dmarc.example.com, starting with p=none.
- 08Send a test message and confirm spf=pass, dkim=pass and dmarc=pass.
| Protocol | Purpose | Typical record | What it verifies |
|---|---|---|---|
| SPF | Authorizes sending infrastructure | TXT record on the sending domain | The sending server |
| DKIM | Adds a cryptographic signature | DKIM TXT and CNAME records generated by Brevo | The message and the signing domain |
| DMARC | Defines alignment and failure policy | TXT record at _dmarc | The visible From domain |
Record names and values differ per account. Always copy them from your own Brevo screen rather than from a generic example.
Why placement drops
Why Brevo Emails Go To Spam Or Promotions
Authentication only proves who sent the message. Placement depends on reputation, engagement and list quality - and Brevo senders hit a few specific problems.
Shared IPs are the default, so authentication and engagement decide your placement.
Transactional and marketing streams share a domain unless you split them onto subdomains.
Free-plan sends carry provider branding that can affect how recipients perceive the message.
Common causes across every sender
- A cold sending domain pushed to full volume in a single campaign.
- Invalid, purchased or long-inactive addresses raising bounce and complaint rates.
- Weak or missing DMARC alignment between the signing domain and the From address.
- Blocklist entries or a damaged IP reputation nobody is monitoring.
- Image-heavy, discount-heavy templates that filters cluster into promotions.

Frequently Asked Questions
Yes. Warmy connects to the domain and mailboxes you send from with Brevo in under 25 seconds. You select Brevo in the provider list, connect your sending domain, and warm-up, placement testing and monitoring start the same day.
The most common causes are a cold sending domain, incomplete SPF, DKIM or DMARC alignment, poor list quality and low engagement. Shared IPs are the default, so authentication and engagement decide your placement. Warmy identifies which of these applies to your domain and fixes reputation automatically.
Create a authenticated sender domain under Senders, Domains & Dedicated IPs → Domains, publish the DNS records Brevo generates (DKIM TXT and CNAME records generated by Brevo), add a DMARC TXT record at _dmarc.yourdomain.com and verify. Warmy validates all three records for you and flags anything that fails.
Yes. A domain with no sending history has no reputation, and mailbox providers filter unknown senders aggressively. Warmy warms the domain up automatically with human-like conversations until it can carry your full Brevo volume.
Yes. Warmy's seed list places your real Brevo template into live mailboxes and reports inbox, promotions or spam placement per provider, including Gmail, Outlook, Yahoo and corporate Microsoft 365 accounts.
No. Warmy works alongside Brevo. Your campaigns, flows and templates stay exactly where they are - Warmy only improves and monitors the reputation of the domain and mailboxes you send from.
