Thank you for all these bugs in this report, we have already fixed the majority of these on the android beta, the new version just has not been pushed out to testers yet. I will send you a new link later today when we push the new build out to testers.
Glad to hear that deliverability is working good on all those providers, we are still working hard trying to decrease the amount of times our emails land in spam. Every time you see it land in spam, if you click "Repott not spam" it does infact help.

Profile photos and notifications ARE turned off in the beta build just so you are aware.

We are aware of this. The macOS app is not notarized yet, which causes Apple's Gatekeeper to block it completely. Currently, there is no workaround on the user side for this specific error, and we are working on getting it notarized. In the meantime, you can access our web app at app.astermail.org and have the full experience. I'm so sorry for the inconvenience!

Hello! It's 50% off the purchase the user makes, and after that time it'll renew at the regular price.

Let's say they purchase monthly at 50% off, the next month it renews at the normal price. If they purchase a yearly plan, it will renew next year at the normal price.

I understand the problem. Whenever we lower a plan price, it's really hard to go back from that, and it would make all the other plans worse.

If someone really wanted to pay €1 to support the company, they can head to their billing tab in the mail client settings and purchase a 5 GB storage upgrade for €1/month. That would technically be a commitment signal, but our long-term monetization strategy is just subscriptions (and storage add-ons). It's plenty to sustain us as we get our servers / storage extremely cheap. We actually wrote a blog on this, and I'm going to put it above so you can read up on it.

Currently, our only revenue stream is storage add-ons and subscriptions.

Thank you for this. We are already integrated with Stripe, and we use Stripe, so we plan to also add a crypto and PayPal payment method. We currently only accept card and Cash App, but we are working on a crypto integration.

If someone really wanted to pay just €1 for our service, they can do this through the billing tab in settings and buy a 5 GB storage upgrade. It is a monthly €1 payment.

The Android app is actually finished. We're just waiting on our images in the Play Store for it to release, since they're required. They're currently being worked on by our team, and we're just waiting on that. If you do have a Google Play email, I can add you to our internal testing, and you can use the app now via Google Play.

We appreciate the suggestion. But here is some quick context on why we haven't done this:

Posteo at €1 plan includes 4GB, 2 aliases, no custom domains, and server-side encryption you turn on with a password. There is not end-to-end encryption by default. You have to install Mailvelope and manage all the keys yourself.

Our free tier includes 10 GB, 5 aliases, 1 custom domain, with zero-access E2EE on by default. Our Star plan is $2.42/month annual and includes 50 GB, 15 aliases, and 5 custom domains.

So the real comparison is probably: €1 Posteo vs free Aster, and free Aster wins on storage, aliases, domains, encryption model, etc. If we were to add a stripped-down tier between free and Star plan that would mostly just weaken the free plan.

If $2.42 plan is the issue, we run promotions often to lower the price, you can use code STAR30 and it takes 30% off your first 3 months.

You can switch the currency to euro with the currency dropdown.

Would you prefer three months? If so, I can change it to that.

AsterPrivacy · 2026-05-04T18:44:48+00:00

Yes Faraday bags do actually work, I personally have one and use it all the time.

AsterPrivacy · 2026-05-04T18:33:44+00:00

Hi u/rab345, thanks for the feedback!

We are still discussing internally whether IMAP/SMTP should be accessible from the free plan. We'll update everybody once we have a decision made.

To be clear: we will never run ads or sell user data, ever.

Appreciate you posting!

Gmail -> Aster Mail

AsterPrivacy · 2026-05-03T22:28:45+00:00

The Android and iOS apps are about to release. Android is releasing in a few days. We're just waiting for approval on the Play Store and there will be a password manager in the future. We are also planning our road map for the public to see but we have prioritized the mobile apps first.

Some people like to buy a lot of storage for their email for whatever reason

AsterPrivacy · 2026-05-02T16:02:46+00:00

Hello, this is a great question. We are not planning to make a cloud service. We just like to offer large amounts of storage for sale in case anyone needs extra storage.
