An odd request

Please quote the email body precisely and in full. Likewise, the headers of the message (you can redact any sensitive information.) A screen shoot would do. A couple things... "Thunderbird" is not an email provider. It's a program that runs on your local computer that allows you manage email on your provider's servers. Are you referring to "Thundermail", the email provider that is still being developed? It is, indeed, accepting requests to join its wait list, but I've never seen them refer to it as "early bird". [later edit - I do find it called an "Early Bird Plan" for $6/month] The most recent status update I've seen from them is from last June: https://blog.thunderbird.net/2026/06/thundermail-june-2026-update-what-we-learned-after-the-first-few-waves-of-invites/ The bit about adding a credit card sounds very suspicious to me. Paddle looks legit to me, but I also find complaints about them. But I'll reserve judgement until I see your actual message.
