Wow Dries, this looks amazing! We love the minimal style of your website. We will give Plunk a try for our next project. Keep up the good work!

I got into the waitlist of Letterbucket in May and I've been using it since them. The team has an amazing response time, everytime I messed up with something, they solved it in minutes

- I'm thrilled to finally see a product that included a environnemental mindset since the design phase.

Killer idea. I think we forget (or don't realize) how powerful email is to reach to our users. Social medias tend to have a huge place now, but having a direct link within our users' inbox... that's great for business.

Let's go! Mail Layer is awesome, we use it in prod to send over 10.000 emails monthly, and the speed at which Mohd ships is incredibly. Highly recommend it!

Hands down the best experience when it comes to Mailing software!

Setting up a solid email stack has always been a headache. Sendkit's AI-native approach is exactly what developers and founders need — reliable, fast, and built for how we actually work today. Big fan!

Transactional email is one of those things nobody notices until it breaks, so having AI agents draft the receipts and password resets is a smart place to start. Do you handle deliverability warmup too?

Hey Uneed — Mike here, CEO @ Unitpost ✌🏻
Most teams I know still run two email tools:* an API for transactions / receipts* a marketing tool for campaignsContacts drift. Two bills. Agents can draft copy, then someone finishes it by hand.
We built one system instead. One contact list, one sending balance, same actions in the dashboard, API, SDKs, and MCP — so Claude, ChatGPT, Gemini, or your IDE can run those actions too. Describe a welcome email or a campaign and Unitpost builds the templates and connects the steps. You approve before anything goes out.
Setup is short: paste your site for Brand Kit, verify the domain.
optional: migrate from Resend / Postmark / Mailgun / SendGrid / Brevo / Loops in < 5 minutes.
Email is live. Automations, SMS, and WhatsApp are next — same system.
What are you all using for email today?

As a premium Proton user, I absolutely recommend ProtonMail. It's fast, efficient, and encrypted!
