Email Deliverability in Braze: Domains, Authentication & IP Setup

In digital marketing, email deliverability directly impacts the success of your campaigns.
You may have created excellent content, but if your message doesn’t reach your audience’s inbox, all your efforts go to waste.

This is where Braze comes in, providing brands with a powerful email infrastructure.
To fully leverage its capabilities, you need to complete a few technical steps correctly — such as domain configuration, authentication protocols, and IP setup.

In this guide, we’ll explore how to optimize email deliverability in Braze, the key technical configurations to consider, and how Omtera’s Braze partnership helps brands achieve higher deliverability success step by step.

Improving Email Deliverability in Braze Email Marketing

Braze offers brands not only the ability to send emails but also the tools to track, optimize, and personalize their deliverability performance.
In this section, we’ll look at how Braze enhances email marketing and how Omtera provides strategic support throughout this process.

With Braze’s advanced infrastructure, brands can:

  • Optimize email send times based on user behavior,
  • Dynamically personalize email content,
  • Deliver a consistent customer experience across multiple channels.

This means not only higher deliverability rates but also stronger engagement and brand loyalty.

Why Is Email Deliverability So Important?

One of the biggest challenges in email marketing is messages landing in spam folders or not being delivered at all.
This not only reduces open rates but also negatively affects brand reputation.

Email deliverability depends on several factors, such as authentication, IP reputation, content quality, and send frequency.
Braze gives brands powerful control over these areas:

  • Domain authentication (SPF, DKIM, DMARC)
  • IP setup and IP warming
  • Send volume management
  • Bounce and spam rate tracking
  • Feedback loop integrations

Omtera effectively configures these features to continuously optimize deliverability rates for Braze clients.

Domain Configuration

Before you start sending emails via Braze, you need to define your brand’s domain (for example, yourcompany.com) within the platform.
This step ensures Braze can securely send emails on behalf of your brand.

Using a Subdomain

Email campaigns are typically sent through a dedicated subdomain to protect the main domain.
For example: mail.yourcompany.com or news.yourcompany.com.

This approach protects your main domain’s reputation and prevents potential spam complaints from affecting your overall email traffic.

Omtera’s recommendation:
Always send emails from a dedicated subdomain reserved exclusively for Braze campaigns. This structure ensures both performance and security.

Authentication: SPF, DKIM, and DMARC

At the heart of email deliverability lies trust.
To prove that your messages truly come from your brand, three key authentication protocols are used: SPF, DKIM, and DMARC.

SPF (Sender Policy Framework)

SPF defines which servers are authorized to send emails on your behalf.
To allow Braze’s IPs to send emails under your domain, you must add the required SPF record to your DNS settings.

DKIM (DomainKeys Identified Mail)

DKIM protects the integrity of your email content.
Braze generates a unique DKIM key for your brand, which you add to your DNS records to verify that emails genuinely originate from you.

DMARC (Domain-based Message Authentication, Reporting, and Conformance)

DMARC builds on SPF and DKIM results to strengthen spam control.
It blocks or quarantines unauthenticated emails and provides regular reports on deliverability and authentication results.

Omtera’s technical team configures, tests, and optimizes SPF, DKIM, and DMARC records for Braze users to ensure higher deliverability and improved sender reputation.

IP Configuration and Warming Process

When you begin sending emails from a new IP address, email service providers such as Gmail, Outlook, or Yahoo don’t yet recognize it.
That’s why your IP must be gradually warmed up.

What Is IP Warming?

IP warming is the process of gradually increasing your email volume over time to establish the new IP’s credibility.
The goal is to prove to mailbox providers that your IP is legitimate, not a spam source, and to steadily improve deliverability.

How It’s Done

  • Start by sending to your most active, engaged users.
  • Increase your send volume every few days.
  • Continuously monitor bounce rates, spam complaints, and open rates.

Omtera customizes the IP warming plan for each Braze client, taking into account send volume, audience behavior, and campaign type to create an optimized schedule.

Additional Tips to Improve Deliverability

Keep Your Email List Up to Date

Invalid or outdated addresses lower deliverability.
Braze provides suppression list management tools to help you maintain a clean sender reputation.

Use Segmentation (Cohort Analysis)

Instead of sending the same email to everyone, segment your audience based on user behavior.
Omtera uses Braze Canvas Flow to build automated segment updates and event-triggered campaigns.

Send Personalized Campaigns

With Braze AI, you can use dynamic content and Intelligent Timing to reach each user at the optimal moment.
This significantly boosts open rates and engagement.
