Throwaway since I’m a former Twilion.

Even though people love Twilio for their developer friendliness and nice APIs, what no one wants to talk about publicly is their disproportionate amount of revenue that comes from spammy behavior. Either as a company or it’s customers.

I was in sales. I saw the revenue numbers and sold these deals. It’s staggering.

Yet wall street looooooves Twilio because of their revenue growth.

Note: Twilio owns Sendgrid.

What I would like to know from a Twilion:

Is Twilio used by commercial parties in the past to participate in voting in the European Song Festival?

Did you mean the Eurovision Song Contest, or something else?

Same here regarding the support. I helped a company migrate to Sendgrid, and right after paying and integrating, we were locked out of the customer panel.

We created a ticket, and a few hours later we were also locked out of the support area. All in all, it took them 7 days from locking us out before we received a human response and they fixed it.

We recently couldn't deliver to Hotmail. It took them 27 days before the first response (P2 Degraded). They didn't fix it, and wanted us to switch plans.

Are you still using them? Why?

We currently still have a subscription, but the project we're using it for became on hold during the Hotmail problem. The project will be cancelled soon, and we'll cancel our Sendgrid subscription.

If the project wouldn't have been cancelled, we would've probably switched to another email service.

After doing some more research, it seems the major alternatives are Postmark, MailGun, and Amazon SES. I liked one comment left by Postmark on another HN post where they say they want high quality senders, so I think I'm going to Postmark...

I've also experienced my IPs getting blacklisted (albeit on the free plan). I can understand this happening (you get what you pay for) but what I can't understand is that their support response was saying that I just had to deal with it rather than switching my IP. I've also used MailGun and not had that problem (although I'm not a fan of the way you can't export logs from them for some reason).

You may have luck with protonmail's paid tiers. I use the free tier currently and have been pretty happy.

Thanks but I host my own email so I'm only looking for an outbound SMTP server. I went to ProtonMail's business page and the pricing plan only shows full email hosting which I don't need.
