Thanks AJ! Yes, Postmark are an amazing company and have built an incredible product. Do you mind if I ask:

a) How you made/came to the decision to use them initially (if you remember?)

b) If there's anything they do / don't do that could help you?

Maintaining reputation is a challenge - in the early phases I'll be ensuring that no one is abusing our service (note that we only allow transactional email) and over the long term we'll build automated techology to help monitor and scale this out.

Thanks Marc, indeed this is spot on.

It's hard to convince anyone to switch unless they're having difficulties with their current provider (I do think that is an ongoing problem for even the larger players, e.g. Sendgrid were getting heat recently: news.ycombinator.com/item?id=…)

An integration with Rails is something I am considering, but I don't want to maintain lots of integrations so I will be selective about which frameworks to target. There's also something to be said about reducing library dependencies for a lot of app developers.

Obviously buying into the market by e.g. offering 12 months free could help but I would prefer to choose customers that are looking for quality service, performance etc. over the cheapest deal.

Thanks for your last comment especially - looking for and finding the right niche, figuring out how/when those developers/companies make their email provider choice and then influencing that choice is going to be my main focus for the immediate future.

There's room for multiple implementations of the same idea - it's actually much rarer for a unique idea to be succesful than a non-unique one. So don't worry if someone copies you, it just means there's a market for your product.

Thanks Marc! This is a great question.

I want to position OhMySMTP as the most developer friendly way to send transactional email. The API is really, really simple (one endpoint with very few options to trip users up), we're focused on getting to inboxes/staying out of spam folders, and we hand-hold users through getting DKIM setup and setting everything up ready to go.

I'll update the landing page to make this clearer.

I see you use sendgrid for wip, was there a reason you chose them?

Looks great and a cool idea, feedback:

• I can't understand the video - it autoplays and there are no browser controls (firefox on macos), so by the time I finished reading the first few sentences on the page I couldn't catch up and I couldn't follow it at all
• I missed your get started button and Create Account button at the bottom, I did see the email box though so I assumed it was the app was unfinished and it was just an email collection page
• The suggestions are really cool! But you should ask some questions upfront to tailor them a bit more (e.g. I got one about Malaysia)
• In suggestions, clicking subscribe doesn't actually subscribe you - you have to click check and then you can subscribe
• When I click on a blog post, it should mark it as read somehow
• Would be great if I could drag items from a list into a new list (e.g. a "To read" list)

I don't use RSS feeds much so take my feedback with a pinch of salt 🙂
