I literally highlighted every paragraph of this post. So many things to agree with. I'm really looking forward to the breakdown of much of what has been teased here. Top of mind: Is Postal the self-hosted transactional mail server ( https://github.com/postalhq/postal )? Been looking at using this for an idea, and wanted to know if there are any obvious gotchas to look out for.

Postal is an amazing project. It just works out of the box. No much config required apart from the DNS. You can set the postal worker/thread count on the Postal config and Mysql connection count based on your machine and that would do. Finding the right numbers based on the CPU/RAM would be trial and error. We were able to achieve over 100 mails/sec on a 36 core system.

Their github issue tracker is pretty active: https://github.com/postalhq/postal/issues/

This was a discussion we had regarding scaling of postal: https://github.com/postalhq/postal/issues/697

On the same line, you should checkout https://listmonk.app/ by @knadh and we use it internally for sending email to our over two million users.

Do you guys provide bug bounty?

Yes they do provide bug bounty and I am still waiting for API credits from past 3 years for finding a bug in API, where anyone can use it for free.

It is great that they fixed it immediately after I sent them the details. Thanks to Nikhil Aralimatti (Business Analyst), who promised that the credits will be there in my account EOD. I should have asked if they live near a blackhole, because it looks like their EOD has not yet come for 3 years.

Apologies. This definitely would've been a genuine case of human error or oversight. There is no logical reason to not issue API credits that were promised. If you are still interested, please write to me and I will get the credits added.

Surely interested, if it's lifetime credits. Because, that's what I saved zerodha from everyone else using your service for free. Unless it is lifetime credits, I don't want to take pain migrating my integration to zerodha for few months of free credits.

I am sending you an email with more details.

Bootstrapped, 10 years old and their tech looks great (from a customer UX perspective). Cool that they’re launching a tech blog. I’ve learned a lot from business engineering blogs over the past decade

New graduate here. Can you share some blogs which could help me ?

There is some reports that they sell your contact information to shady investment marketing companies.

I've talked about the technical issues in a couple other responses on this post. About spam, we've been working with the capital markets regulators, cyber crime units (Police), and TRAI (telecom regulator). It is a nasty issue that plagues all capital markets institutions in India. I'd gone into some detail on the data leaks on this Reddit AMA last year: https://www.reddit.com/r/IndiaInvestments/comments/bhv18e/we...

Ah..Ok, so contact information may have been leaked at various stages of the regulatory process or even at the Telco..

Good that you are taking action on the spam callers and hopefully other improvements have reduced the service interruptions. The regulatory environment possibily does not look with kind eyes on new entrants in the financial services industry. So I think you might have had many struggles to reach where you are.

I really didn't intend to shower negative sentiment about the service, only to highlight a few complaints I have heard, but later I saw it had become the topmost comment.

Agree with the contact sharing thing. As soon as I registered I started getting telemarketing calls from many "Investment Research" companies giving me "recommendations".

Kailash Nadh, zerodha's co-founder, is an active investor as well through the rainmatter startup incubator [0]. There's been quite a boom in the fintech space in India for quite some time now, but zerodha is one of the first generation companies that survived through thick and thin. Indian fintech and edtech companies invite a tonne of interest from YC, in particular, and so, dare I say, the going has got a bit easie…

I'm not an expert in trading, but I thought that you could only invest in the indexed/mutual funds available in your country? I'm not sure your average Indian can, say, start putting money in any Vanguard fund available to Americans.

You can directly invest in NASDAQ and NYSE via https://greentiger.co/

It’s a YC funded company too.
