Step-by-Step Guide on How to Setup SendGrid on a Bubble App

This guide requires your Bubble App to already be connected to a custom domain, and we’ve written an article with that step-by-step guide on how to set up your own custom  domain.

Step 1: Set Up Your SendGrid API Key

First, you’ll need to create an API key in your SendGrid account:

1. Log in to SendGrid and go to your Dashboard.
   
   
2. In the sidebar, click Settings → API Keys.
   
   
3. Click Create API Key.
   
   
4. Name it something like Bubble App Email Key.
   
   
5. Choose Full Access (or Restricted if you know what permissions you want).
   
   
6. Click Create & View.
   
   
7. Copy your API key. You won’t see it again!
   
   

Step 2: Paste Your API Key into Bubble

1. Open your Bubble app.
   
   
2. Go to Settings → Email.
   
   
3. Select Send emails using SendGrid.
   
   
4. Paste your API key into the field.
   
   

At this point, Bubble will try to verify your sender identity. If you haven't already set up an email like admin@yourdomain.com, you may hit a verification error.

Let’s solve that.

Step 3: Fix Sender Verification Issues (Two Methods)

Method 1: Create an Email Alias (admin@yourdomain.com)

This is the quickest solution for Google Workspace users.

1. Go to admin.google.com.
   
   
2. Navigate to Users → Select your user.
   
   
3. Click Add Alias.
   
   
4. Enter: admin@yourdomain.com.
   
   
5. Save and wait ~15 minutes.
   
   
6. Return to SendGrid → Sender Authentication → Single Sender.
   
   
7. Enter your name and the admin@ alias you just created.
   
   
8. Click Create.
   
   
9. Check your inbox and click the verification link.
   
   

Once confirmed, your sender identity is verified and you can now send emails from Bubble.

Method 2: Authenticate Your Domain via DNS

This method is preferred for more flexibility and long-term use.

1. In SendGrid, go to Settings → Sender Authentication → Domain Authentication.
   
   
2. Choose Other as your DNS host.
   
   
3. Enter your domain (e.g., yourdomain.com) and click Next.
   
   
4. SendGrid will give you a list of CNAME records.
   
   
5. Go to your domain registrar (like GoDaddy or Namecheap).
   
   
6. Navigate to DNS settings.
   
   
7. Add each CNAME record provided by SendGrid.
   
   
8. Return to SendGrid and click Verify.
   
   

⏱ It may take 1–2 hours for DNS changes to propagate.

✅ Once verified, you can send from any email address using your domain—like support@yourdomain.com or info@yourdomain.com.

Step 4: Finalize Integration in Bubble

Now that your sender identity is verified:

1. Go to your Bubble app’s Settings → Email tab.
   
   
2. Fill in the Sender Name (your app or company name).
   
   
3. Use the verified sender email (e.g., admin@yourdomain.com).
   
   
4. Click Verify SendGrid Key.
   
   

If everything is set up correctly, you’ll see a success confirmation.

Step 5: Send a Test Email

To confirm everything works:

1. Create a test page with a Button.
   
   
2. Add a Workflow → Send email action.
   
   
3. Use your verified sender email.
   
   
4. Click the button.
   
   
5. Check your inbox.
   
   

If the email arrives, congratulations! You’ve successfully connected SendGrid to your Bubble app.

Why Email Matters for AI and MVP Apps

Email is one of the most powerful channels for automated workflows. Whether you're launching a platform with smart notifications or an internal tool for enterprise teams, getting your email setup right ensures:

• Reliable user onboarding
  
  
• Payment confirmations
  
  
• Password resets
  
  
• Triggered alerts from AI models or backend workflows
  
  

That’s why most high-growth startups and top AI software agencies prioritize integrating transactional email systems early.

Benefits of Using SendGrid with Bubble

Integrating SendGrid into your Bubble app brings significant advantages, especially for founders building scalable MVPs or automation-driven platforms.

As a cloud-based email delivery service, SendGrid ensures your transactional and marketing emails are delivered reliably—without the hassle of managing your own SMTP server.

One of the biggest benefits is deliverability. SendGrid is built to handle large volumes of email and offers tools like domain authentication, suppression management, and reputation monitoring, helping your messages reach inboxes instead of spam folders.

SendGrid also supports template-based emails with dynamic fields, which is a huge win for workflow automation tools and apps with custom notification logic. You can easily design branded templates and trigger them from Bubble workflows—without writing code.

Another major benefit is scalability. Whether you're sending 100 emails per day or 100,000, SendGrid can scale with your app. Its robust API integrates seamlessly with Bubble software development, making it ideal for startups and teams using no-code to build fast.

Finally, SendGrid’s analytics dashboard provides insight into opens, clicks, bounces, and more—helping MVP development agencies and AI app development agencies fine-tune engagement and optimize communication strategies.

In short, if you're building with Bubble, SendGrid is the smartest way to manage email at scale.

Use Case: AI and Workflow Automation Tools

If you're building a product using Bubble software development and integrating workflow automation tools, SendGrid helps you create a seamless user experience. Big House has implemented similar setups for clients building:

• AI chatbots with real-time alerts
  
  
• Custom dashboards that trigger transactional messages
  
  
• SaaS platforms with advanced notification systems

Why Email Automation Matters in MVP and AI App Development

For early-stage founders and product teams, setting up reliable email workflows is critical—especially if you're launching an AI-powered app or a minimum viable product (MVP). From onboarding sequences to AI-generated report delivery, email automation is a cornerstone of both user experience and backend operations.

Tools like SendGrid allow non-technical teams using Bubble software development to implement advanced email logic without writing server-side code. For example, you can automate emails when users complete key milestones, receive AI-generated insights, or trigger events via workflow automation tools.

If you’re working with an AI development agency or a MVP development agency, chances are they’ll recommend integrating transactional emails early in the build. Why? Because user feedback often starts with emails. Whether it’s confirmation, support requests, or engagement data, automated email is how users communicate with your product before you ever hear from them directly.

Integrating SendGrid early enables faster iteration, improves user trust, and ensures that vital messages land in the inbox—not spam. It’s one of the most effective tools you can add to a no-code stack, especially when you’re moving fast with limited dev resources.

SendGrid vs Other Email Providers: Why It’s the Better Fit for Bubble

When comparing SendGrid to other email delivery providers like Mailgun, Amazon SES, or SMTP2Go, the choice for Bubble users becomes clear. SendGrid stands out for its ease of use, native integration with Bubble.io, and powerful developer tools—making it a top choice for both beginners and professionals.

Unlike more complex APIs like Amazon SES, SendGrid is beginner-friendly. It offers a straightforward UI for managing templates, sender identities, and email analytics. Plus, it comes pre-integrated as the default transactional email provider inside Bubble, streamlining the entire process of connecting and sending.

For companies working with a Bubble.io certified agency or best Bubble agency like Big House Technologies, SendGrid also offers deep customization for scale. You can send emails dynamically using user data, trigger workflows, and even implement A/B testing for engagement optimization.

Compared to traditional email providers, SendGrid delivers high inbox rates, detailed reporting dashboards, and proactive suppression list management. It’s built for modern apps—especially those built with Bubble software development and AI workflow automation tools.

If you want peace of mind that your critical emails won’t go missing, SendGrid is the provider of choice.

How SendGrid Powers AI-Driven User Notifications

If you're building an AI app—for example, a tool that generates reports, forecasts, or smart suggestions—email is often the best delivery method. With SendGrid, you can send highly personalized, data-rich messages generated in real-time by your AI engine.

This is especially useful for apps built with workflow automation tools, where AI models trigger emails based on user activity, time-based events, or predictions. For instance, an AI-powered sales platform might email clients insights every Monday morning. Or a smart analytics dashboard could alert users when anomalies are detected.

By using Bubble in tandem with SendGrid, non-technical teams can create sophisticated email logic using simple workflows. Each message can pull from dynamic Bubble data sources—user names, AI recommendations, or usage metrics—and deliver highly relevant messages.

This makes SendGrid an essential tool for any AI development agency looking to scale their app’s impact. With domain authentication, link branding, and API-level control, you can ensure emails look trustworthy and deliver real value.

Ultimately, SendGrid bridges the gap between the intelligence of your AI and the personal touch of great communication.

The Role of SendGrid in Enterprise App Development

For companies investing in enterprise app development, especially using no-code platforms like Bubble, email infrastructure cannot be an afterthought. At scale, email deliverability, compliance, and reporting become essential components of operational success.

SendGrid brings enterprise-grade tools to the table, making it easy for IT teams and Bubble software development partners to manage email workflows across departments, platforms, and use cases. With features like domain-level authentication, IP whitelisting, and subuser accounts, it’s ideal for larger teams or regulated industries.

When paired with Bubble, SendGrid enables seamless internal workflows—like automated reports to managers, onboarding messages for HR, or alerts from AI-powered monitoring systems. These types of integrations are exactly what top AI software agencies and Bubble.io certified agencies use to deliver measurable value in enterprise environments.

In addition, SendGrid’s real-time analytics dashboard helps enterprise teams measure performance across campaigns and departments. You can track email open rates, engagement, bounce rates, and more—all of which are crucial for compliance and optimization.

So whether you're sending 10 or 10,000 emails a day, SendGrid provides the control, reliability, and insights needed for enterprise success.

Key Features That Make SendGrid Ideal for Bubble Apps

What makes SendGrid such a perfect fit for Bubble.io applications? It’s a combination of powerful features, ease of integration, and flexibility—especially when you're building fast and want to stay focused on product development.
