Warm up your Sendinblue (Brevo) inbox.
Whether you call it Sendinblue or Brevo, warmup builds the sender reputation that gets your campaigns to the inbox. Connect via SMTP credentials in minutes.
Why warm up your Sendinblue/Brevo inbox?
Brevo (formerly Sendinblue) handles transactional, marketing, and outbound email. But mailbox providers score reputation per sender domain — so your Brevo-routed cold or marketing campaigns need warmup history to land in the inbox.
Cold sends through Brevo hit spam
Without engagement history, mailbox providers treat new Brevo-routed domains as low-trust. Cold outbound and aggressive volume drop into spam.
Warmup builds cross-provider trust
Real inboxes engage with your Brevo-sent warmup messages. Reputation builds across Gmail, Outlook, Yahoo so your campaigns reach the inbox.

Frequently asked questions
Is this for Sendinblue or Brevo?
Same service — Brevo is the rebrand of Sendinblue (rebranded May 2023). The SMTP integration works identically. We support both old and new account naming.
How do I find my Brevo SMTP credentials?
In Brevo, click your account → SMTP & API → SMTP tab. You'll see your SMTP login (your Brevo email) and SMTP key. Copy both into Warmup Inbox.
Does this work with Brevo's transactional templates?
Yes — warmup runs in parallel to your transactional and marketing sends. Your templates, automations, and contact lists keep working as before; warmup is a separate background flow.
Will warmup affect my Brevo plan limits?
Warmup sends count against your Brevo daily/monthly send quota. A Pro Warmup Inbox plan adds about 7,500 messages/month per warming inbox. Check your Brevo plan limits.
How long until Brevo reputation improves?
Most teams see open-rate and inbox-placement lift within 14–21 days. Brand-new Brevo domains take 30–45 days for full warmup maturity.
