The rise of no-code development has fundamentally changed how products are built.
Today, founders, startups, agencies, and businesses can launch applications significantly faster without managing complex backend infrastructure from day one.
One of the platforms leading that movement is Bubble.io.
Bubble has enabled thousands of teams worldwide to build a wide range of applications.
- SaaS platforms
- Marketplaces
- Internal tools
- AI applications
- Client portals
- MVPs
without writing large amounts of code.
But while building products has become easier, communication infrastructure still remains one of the most fragmented parts of the stack.
Most Bubble applications eventually require several key capabilities.
- Transactional emails
- Marketing campaigns
- User onboarding flows
- Notifications
- Email tracking
- Custom domains
- Automations
- Delivery analytics
And this is where many teams end up stitching together multiple tools.
At Keplars, we wanted to simplify that experience.
That's why we're excited to announce the official Bubble.io integration for Keplars.
Why We Built the Bubble Integration:
While speaking with founders and teams building on Bubble, one common challenge kept appearing.
The product itself could be launched quickly.
But communication workflows became increasingly difficult as the application grew.
Teams often found themselves managing multiple disconnected services.
- SMTP providers
- Email APIs
- Marketing tools
- Tracking platforms
- Domain configuration
- Authentication records
- Automation systems
across multiple disconnected services.
The result was unnecessary complexity around something that should be straightforward.
Our goal with Keplars has always been to make email infrastructure significantly easier for both technical and non-technical teams.
The Bubble integration is another step toward that goal.

What the Integration Supports:
With the Bubble + Keplars integration, developers and no-code builders can now manage communication workflows from a single platform.
Transactional Emails:
Send critical application emails including welcome emails, password resets, OTP verification, account notifications, billing emails, and order confirmations directly from Bubble workflows.
Marketing Emails:
Manage newsletters, campaigns, product announcements, promotional emails, and re-engagement workflows without requiring separate email infrastructure.
Real-Time Tracking:
Visibility is a major part of modern communication systems. Keplars provides real-time tracking for sent emails, delivered emails, open events, and click events — allowing teams to understand exactly how users interact with every communication.
OAuth-Based Sending:
Managing email credentials can become difficult as products scale. Keplars supports OAuth-based sending, helping simplify authentication workflows while improving security and management.
Custom Domains:
Businesses need communication that reflects their brand. The integration supports custom domain configuration, allowing teams to send emails directly through their branded domains.
APIs, SMTP, Webhooks, and SDKs:
For teams extending beyond no-code workflows, Keplars provides Email APIs, SMTP support, Webhooks, and SDKs across 11 programming languages. This makes it possible to combine Bubble applications with more advanced backend workflows whenever needed.
Common Bubble Use Cases:
The integration is designed to support a wide range of Bubble applications.
SaaS Products:
Typical workflows include user onboarding, trial reminders, product notifications, subscription updates, and customer engagement campaigns.
Marketplaces:
Communication becomes critical between buyers, sellers, vendors, and service providers. Keplars helps automate these interactions reliably.
AI Applications:
Many AI-powered products require report delivery, async notifications, workflow updates, and user summaries. Email infrastructure often becomes a core part of the product experience.
Internal Tools:
Organizations frequently use Bubble for operations platforms, CRM systems, internal dashboards, and approval workflows. Automated communication plays an important role in these environments.
Simplifying Infrastructure Complexity:
One thing we've consistently observed while building Keplars is that most teams don't want to spend time managing communication infrastructure.
They want to build products.
Yet communication systems often require SMTP configuration, DNS records, tracking systems, automation tooling, and deliverability management — all spread across different services.
The Bubble integration helps consolidate those workflows into a simpler experience. Instead of managing multiple providers separately, teams can centralize communication infrastructure through Keplars.
Built for Both Technical and Non-Technical Teams:
A core principle behind Keplars is accessibility.
Many email platforms assume every user is highly technical. But modern products are increasingly built by founders, operators, agencies, growth teams, product teams, and no-code builders.
The Bubble ecosystem reflects that shift.
That's why Keplars focuses on reducing setup friction while still providing the flexibility needed for advanced communication workflows.
Setup takes only a few clicks. Learn more about the platform at keplars.com.
Getting Started:
Getting started with the Bubble integration is straightforward.

Looking Ahead:
The future of software is increasingly moving toward faster development cycles, no-code platforms, AI-assisted workflows, and lean product teams.
Communication infrastructure needs to evolve alongside that shift.
Our goal at Keplars is to make setup, sending, tracking, and automation significantly simpler — regardless of whether you're building with code or no-code tools.
We're excited to support the Bubble community and help more builders launch scalable communication workflows without unnecessary infrastructure complexity.
