The history
Stripo launched in 2016 to build a faster, smarter email editor. We cut production time by over 50% with our WYSIWYG builder and became one of the first to fully support AMP for interactive emails in 2019. Since then, we’ve reached 1M users (Oct 2023), released a new flexible editor (Aug 2024), and introduced an AI Assistant to generate copy and brand-aligned content (Jan 2025).
Our role
This project has always been and stays self-funded. Thanks to our engagement and business analysis, we spent 1/3 of the budget the customer aimed to spend, letting him grow fast and invest more in marketing. Today we provide full-stack development and support for this SaaS, including business and financial monitoring, drastically reducing all the costs for IT engineers
Marketing team
After one year of development, we set up a dedicated marketing team that grew from 2 to 21 experts working full-time. They support the website, do branding, copywriting (8 languages), do videos for the Youtube channel, SEO, and link building. All our marketing activities pushed this SaaS to the TOP 3 in the world and turned it into a stable source of customers, recurring revenue, and ensuring stable monthly growth.
Long term relations
The team we created became a dedicated development team for the customer and took responsibility for all technical jobs. We started from nothing, passed through 4 principal pivots and today, we turned this SaaS into a secure, high-performance and scalable system capable of satisfying the needs of large companies. The team is still growing and our recruiters are working to close existing vacancies.

Services Used
Light Emails
Gmail has a size limit of 102KB for each email message. Once that limit is reached, the remaining content is clipped and hidden behind a link to view the entire message. That’s why creating something that wouldn't generate any extra HTML & CSS code for emails was necessary.
Drag&Drop Email Builder
The user-friendly email builder allows you to create any email by dragging and dropping the necessary elements into your template. In addition to the Drag-n-Drop email builder, we developed the HTML & CSS code editor. It can be used to code emails from scratch or edit and add custom elements to the emails that you create with our Drag-n-Drop builder. The D-n-D and HTML & CSS code editors can be used simultaneously without switching.
Export To More Than 80 Systems
For ease of use of the product, we created an export to more than 80 popular ESP systems and email services such as Gmail, Mailchimp, Hubspot, GetResponse, Zapier and Webhook. Stripo was the very first solution that provided an opportunity to export email to Outlook. Also, we added the possibility to export emails to different formats - PDF, HTML or as an image.
AMP for Emails
In 2019 Google rolled out AMP for Gmail, allowing it to add real-time and dynamic content to emails. After 2 sprints, we provided this functionality into Stripo and integrated the possibility to mark blocks as AMP or not. This solution helps to adjust emails for different systems and needs, add to emails custom forms, carousels and interactive banners.
Collecting users’ feedback
Allow recipients to leave comments and share their opinion directly in emails. AMP forms embedded in emails generate 5X times more feedback than traditional external forms.
Real-time content
Information in emails gets updated the minute recipients open them. In this way, you share only fresh content with your users. It also inclused updating product card descriptions, fresh copy in welcome emails, adjusting stock quantity, and even syncing data in games after interaction with an email.
Dynamic product blocks
Update the quantity, prices, product images, and descriptions of your products in emails even after they are sent. Provide recipients with up-to-date information based on their interactions and preferences. Depending on parameters like gender, country, or behavior, dynamically display relevant products to make each email more personalized and effective.
Interactive Modules Generator
Enhance customer engagement with Stripo's Interactive Modules Generator. Create dynamic, interactive content without any coding. With features like polls, quizzes, and more, you can captivate your audience, learn about their preferences, and strengthen customer relationships - all within the email.
Email Testing in One Window
We have developed a user email testing tool to ensure that email will be displayed correctly in over 90 ESP and email service systems. The main challenge was to make testing in one window for all systems and devices (mobile, desktop) without switching.
Modules Library
Stripo's Module Library includes reusable elements like footers, blog posts, and product carts to streamline email creation. By integrating features like product reviews for collecting feedback directly via emails, we help marketers save time and improve engagement.This has reduced email creation time from 2.5 hours to just 30 minutes!
Email Sharing & Commenting
We developed a feature that enables users to share emails and templates within their workspace, inviting others to view or edit, with roles like Admin, Designer, Writer, Proofreader, and Viewer.
Additionally, we introduced a commenting system, allowing team members to provide feedback directly within the platform. No registration required, and comments can be made anonymously. This feature enhances collaboration and streamlines the email production process.
Translations Inside Editor
We’ve enhanced the email editor to allow seamless translation of emails from one language to another directly within the platform. This feature helps proofreaders view translations in context, ensuring a more accurate and efficient review process. With translations displayed directly in the email templates, teams can work faster and avoid costly errors, leading to a smoother, more streamlined user experience.
Brand Guidelines
We developed a feature that allows users to store and manage email design styles and brand assets in one central location. This ensures consistency across all emails and helps onboard new designers quickly, maintaining a strong and cohesive brand identity.
AI Assistant
We integrated an AI Assistant within the email editor to assist in generating copy, subject lines, and brand-aligned campaigns directly in the editor. This tool was developed to significantly reduce the time spent on content creation, helping teams produce high-quality emails more efficiently and with minimal manual effort. The AI Assistant is accessible through the AI Hub menu.
What is the AI Hub?
The AI Hub is a dedicated space within the Stripo account where users can automatically generate email content using generative AI. It’s located on the sidebar of your account. From the AI Hub, users can configure and control every aspect of email creation, from initial content generation to final design, ensuring that the emails align perfectly with the brand’s voice and objectives.
AI Image Generation
We developed an AI image generation feature that allows users to create custom images for emails simply by describing what they need. This tool automates visual content creation, reducing reliance on graphic design tools and saving time on image production. Additionally, we integrated two powerful AI-driven options:
- AI Alt Text Generation: Automatically generates descriptive alternative text for images, improving accessibility and SEO.
- AI Image Generation Models: Enables users to create AI-generated images directly within the email editor, further streamlining the design process.
Real-Time Co-Editing
We developed a real-time co-editing feature that allows multiple users to collaborate within the email builder simultaneously. This functionality ensures that changes are reflected instantly across the platform, significantly speeding up the email production process and enhancing teamwork. The feature was specifically designed to improve collaboration and streamline revisions, making it easier for teams to work together efficiently.
The co-editing function in the email template editor enables team members to work on the same email template at the same time, enhancing teamwork and facilitating smooth collaboration across different roles, such as designers, copywriters, and marketers.
