Thank you for your feedback; it's incredible. Precise and effective, it's exactly what helps us improve the product. So, first of all, thank you!

I understand your comment regarding billing, and we will work on that to make it easier to understand.

Regarding the daily limit, Mailhub is a v2 product of a previous one called Mailwind, which was a similar "plugin." We decided to rebuild everything from scratch—the code, branding, everything. So, we've already encountered scammers as you described and have implemented an effective system to prevent that:

Maximum security on our payment provider (Stripe Radar) A custom AI that analyzes sent emails (by code or template) and reviews the content. In case of excessive fraudulent sending, the account can be blocked. Thank you for the warning; we've already dealt with this kind of problem. I understand your request concerning SMTP. We aren't ready for this service yet, but we will work on it very soon. Do you have a contact I could use to alert you when this service is implemented?

As for the "to" field, you’re right, it could be an issue. We prioritized ease of integration but will ensure this feature is monitored closely.

Regarding the typo, fix in progress, thank you!

You're welcome about the feedback.

As for contacting me, not really, I enjoy my anonymity of Hacker News and anyways, we are satisfied-ish with SendGrid right now. So even if you got the feature, we are not potential customer at this time. I'll keep your company in mind in case that changes with SendGrid or I change companies.

EDIT: When I say Ops person in charge of email, email isn't my sole focus, in fact it rarely comes up. However, when SendGrid misbehaves, I'm first one that is called.

I understand your desire for anonymity, and I respect that.

Thanks again for your valuable feedback; it’s definitely one of the most relevant, even though all feedback is important!

You seem to be a great asset to your team, so it's no surprise they call on you, haha. Best of luck moving forward, and thank you!

> A custom AI that analyzes sent emails (by code or template) and reviews the content.

Referring to proprietary logic (fuzzy or not) as AI?

Both There are rules for filtering, but there is also an AI that allows checking the potential danger of the content.

so emails sent are shared with third parties and added to models?

I didn’t understand, can you explain What do you mean ?

Does this call 3P LlM apis like chaptGPT? Does it send any of my email content and/or recipient data into those 3P?

That is a nonstarter for some companies. Not saying it’s the wrong choice, but it will narrow your market.

We do not wish to reveal the system that has been implemented to detect potential fraud on a public forum like this one, but I can assure you that no confidential information can be disclosed to third-party services. While we may occasionally use services like this, we ensure that no sensitive data is sent, as long as the Mailhub service is used correctly.

What do you define as confidential information? Not trying to be snarky - just wondering if the data I send you goes to any third parties.

he already said they use 3p services "like these" now it's just a matter of playing with words so they decide how much of your data and meta data is fair game

Hacker News delivers again. What an incredible example of quality feedback from a would-be customer. As one of Mailgun founders, I can also confirm/agree with all of the suggestions above.

> Telling you now, someone will sign up with stolen credit card, spam like hell and you will be left with clean up. Been there, done that.

Ignoring this advice killed some companies in this space.

Exactly, it's incredible. It's a pleasure to exchange like this. As mentioned earlier, we've already experienced similar issues and have done everything we can to prevent it from happening again. Thank you for emphasizing this point, especially considering that Mailgun is a pillar in the field.
