About
Say goodbye to endless hours managing your inbox. Say hello to MailSpresso. MailSpresso helps you respond to emails and compose new emails more efficiently. Why choose MailSpresso? MailSpresso works directly in your Gmail drafts. It analyzes the context of your received emails and crafts responses accordingly. You can refine your replies by selecting a tone, determining the length, and adding relevant keywords and short sentences. Additionally, it can generate new emails (incl. subject lines) based on your keywords and short sentences. Watch a demo video of MailSpresso in action: https://www.youtube.com/watch?v=A_HNSko75P0 All features at a glance: 📢 Tone: Choose from four different tones to accurately convey your message - be it friendly, excited, urgent, or angry. 👟 Quick replies: With the "thumbs up" or "thumbs down" button, you can generate a positive (yes) or negative (no) response. 📏 Email length: Adjust the length of your message according to your needs - be it short, medium, or long. 🔑 Keywords & short sentences: Enter relevant keywords in the input tab. Then, click on the button "Write" to generate a complete email. ✨ Dynamic generation: Each time you click on the button "Write", it generates a new email variation. 🌎 Language: MailSpresso can craft emails in multiple languages, ensuring seamless cross-border communication. Powered by OpenAI & ChatGPT. ***PLEASE NOTE: After installing the MailSpresso Chrome extension, you will need to enter the API key from your OpenAI account to activate the extension. Keep in mind that while MailSpresso is free, OpenAI charges based on your API key usage. For example, generating 450 emails in English costs around $5. Prices may vary for other languages; generating 350 emails in German costs approximately the same.*** Credits: Project initiator: Andreas Schneider - Proarbeit AG Co-creators: Raphael Ernst & Sujan Thapa
