Looks like that Wave thingy sends emails with a plaintext part which is empty, i.e. you just get an empty mail when viewing them in plaintext format. This caused me to ignore those until now, when I investigated what was going on :wink: Not sure if there's anything we can do about this, but I guess we should at least let their support know.

Fortunately we are using ti.to for conference tickets then...
Next year I will send the fee invoices directly.

Non-equivalent HTML and plaintext versions of an email are not standards compliant. But it's not that anyone cares :)
