subject line
The line in an email, letter, or form that briefly states the content or topic of the message.
Bitte geben Sie im Betreff Ihrer E-Mail immer die Rechnungsnummer an.
Please always include the invoice number in the subject line of your email.
'Der Betreff' (the subject line) is the noun related to the verb 'betreffen' (to concern). It therefore names the topic that the message concerns or deals with.

Common phrases are 'im Betreff angeben' (to state in the subject line), 'der Betreff lautet' (the subject line reads), or 'etwas in den Betreff schreiben' (to write something in the subject line). The line itself is often called the 'Betreffzeile' (subject line).
Schreiben Sie bitte Ihre Kundennummer in den Betreff.
Please write your customer number in the subject line.
In formal letters and emails, 'Betreff' (subject) is often abbreviated as 'Betr.', followed by a colon.

topic / theme
Thema refers to the content of an email. Betreff, by contrast, is the specific line that briefly summarizes this content. For the subject being discussed, use Thema; for the labeled line of the message, use Betreff.
Im Betreff meiner E-Mail steht kurz „Verschiebung unseres Termins“.
The subject line of my email briefly says, “Postponement of our appointment.”
Das Thema meiner E-Mail ist die Verschiebung unseres Termins.
The topic of my email is the postponement of our appointment.
