respatch: api based dynamic transactional email provider

Hello! I've been building a lot of SaaS products lately and I've always found building the last few steps to be the hardest, the billing, invoicing, forgot password emails, invoice emails, etc. So I built a simple tool that allows you to input your SMTP credentials from your email provider (Amazon SES, Mandrill, PostMark, SendGrid, etc) and send dynamic emails based on which template you select and variables you set. At the moment I have 3 templates, (a completely custom template is coming within a week or less which will allow you to basically create a complete email from API), 2 languages (looking to see which languages people want) and it dynamically adapts (logo primary color is used as button color, has complete dark mode support, etc). The emails are also fully accessible, tested using screen readers and Litmus and tested for issues/fixed if needed. Let me know your thoughts or if you have any feedback/questions/comments. Thanks!
