Description

Coldletter is an email design and automation layer that helps teams create, manage, and send product emails without replacing their existing email provider. It connects with delivery services such as SendGrid, Postmark, Amazon SES, Mailgun, Resend, and SparkPost, giving companies flexibility while keeping sending infrastructure intact. The platform includes a visual editor where teams can build templates, add variables, reuse blocks, and preview emails across clients such as Gmail, Outlook, and Apple Mail. Every template is designed to be responsive, accessible, and safe for dark mode by default. Developers can trigger templates through a single API request while Coldletter handles rendering, data merging, routing, retries, suppression, and idempotency. Marketing, lifecycle, design, and product teams can use the platform to manage email content without constantly relying on engineering for every change. Journey automation tools allow users to create workflows based on events, schedules, engagement, attributes, or A/B testing paths. Version control, template diffs, rollbacks, localization, test sends, roles, approvals, and analytics help teams manage production emails with more confidence. Coldletter gives organizations a structured way to build polished product emails while improving collaboration between technical and non-technical teams.

Description

Customize your emails by including any desired fields sourced from Google Sheet columns, while also tracking when emails are opened and monitoring link clicks within those messages. Take advantage of email templates that can be created and utilized directly in Gmail, and assess the effectiveness of these templates through performance tracking. Design aesthetically pleasing templates suitable for newsletters or outreach efforts, and incorporate variables for a personalized touch in your emails. With MergeMail, you can seamlessly connect with over 1,500 different tools via Zapier, including integrations with popular platforms like Salesforce, HubSpot, Google Sheets, and Slack. Preview your emails for accuracy and maintain full confidence in your content before dispatching, while providing recipients with the option to opt out of future communications. On our Premium and Team plans, you can send unlimited emails through Delivery Integrations, utilizing your own email service to ensure complete control over your communications. Evaluate the success of various campaigns and templates, and keep track of conversion rates through automatic UTM codes. You can also easily share templates and campaigns with your team members, and simply place a link or image in a designated column to use it as a variable for further customization. This comprehensive email management system empowers you to enhance your outreach efforts effectively.
