Free SMTP server

Award-winning free SMTP server

Free SMTP services like Gmail and Outlook aren’t designed for sending mass emails or large volumes of transactional emails. Trust an SMTP relay service that’s been set up for delivering bulk emails.
 
<ul>
 	<li>Specially configured SMTP servers support high-volume email sending with great scalability</li>
 	<li>Brevo is an SMTP service provider built on reliable infrastructure</li>
 	<li>We send millions of emails for our clients every day</li>
</ul>

Send bulk email

Brevo’s free SMTP server is backed by dedicated infrastructure and resources to make sure your emails reach the inbox (and avoid the spam folder).
 
<ul>
 	<li>Closely monitored shared IPs</li>
 	<li>A team of experienced email deliverability experts</li>
 	<li>Rigorous validation process to keep spammers out</li>
</ul>

Reliable deliverability

Brevo’s SMTP server ensures your time-sensitive transactional emails are delivered on time, every time.
 
<ul>
 	<li>50% of emails delivered within 1 second</li>
 	<li>99.98% of SMTP emails delivered in under 20 seconds</li>
</ul>

Rapid email delivery

Our sender reputation is well established among email clients (Gmail, Outlook, etc.) and we maintain strict control over all our IP addresses. By choosing to send over our free SMTP server, you get to benefit from the deliverability of an established SMTP service provider.

Trusted sender reputation

No credit card. No commitment.

Send confidently with Brevo’s SMTP server

Trust our SMTP relay service to deliver your most important customer updates: account activation emails, order confirmations, shipping notifications, receipts, password resets, security alerts, and all other use cases covered. Including beautiful and responsive ready-made email templates.

Send transactional emails

Bring your vision to life and customize your email campaigns with code. Our API works alongside the most common programming languages, so your team can create any email if the ready templates don’t fit your needs.

For developers too

Just plug our SMTP credentials into another service to have these third-party emails sent through Brevo. Take full advantage of our cloud-based SMTP mail server’s established sending reputation and reporting features.

Send emails from other apps and websites

Trigger custom email automation workflows based on user activity and website behavior. Never miss an opportunity to engage with our reliable SMTP relay.
 
<ul>
 	<li>Ready-made workflows and templates</li>
 	<li>Multi-channel workflows for email & SMS</li>
 	<li>Emails triggered by link clicks and visits to your WordPress site or other third party app</li>
</ul>

Automation workflows

Our free SMTP relay server gives access to advanced reporting features so you’ve got the data and insights you need to consistently improve. Transactional logs are stored indefinitely so you can also go back and check.
 
<ul>
 	<li>Real-time delivery rates and performance metrics</li>
 	<li>Clear, easy to digest data for rapid analysis</li>
 	<li>Custom webhooks for instant updates however you want to receive them</li>
</ul>

Analyze email delivery and engagement

Brevo offers a number of features to help marketers maintain and protect their sender reputations.
 
<ul>
 	<li>Hard-bounce pooling to avoid sending any more emails to hard bounce contacts (automatic unsubscribe)</li>
 	<li>Dedicated IPs available for high-volume senders on paid plans</li>
 	<li>Split transactional and promotional emails into different streams (by sender and IP address)</li>
 	<li>Domain name authentication (SPF, DKIM, and DMARC) to validate your sender signature</li>
</ul>
