Usage tips
Word family
'Drittens' (thirdly) belongs to a series of adverbs that structure lists: erstens (firstly), zweitens (secondly), drittens (thirdly), viertens (fourthly), etc. They are formed from ordinal numbers (erste, zweite, dritte) with the ending '-ens'.
EXAMPLE
Meine Gründe sind: erstens, die Kosten; zweitens, der Zeitaufwand; und drittens, das Risiko.
My reasons are: firstly, the costs; secondly, the time required; and thirdly, the risk.
Sentence position
When 'drittens' (thirdly) is at the beginning of a sentence (position 1), the verb follows directly after it in position 2. The subject then moves behind the verb.
EXAMPLE
Drittens müssen wir die Ergebnisse analysieren.
Thirdly, we must analyze the results.

drittens vs außerdem
also / besides
'außerdem' and 'drittens' can both introduce another point in an argument. 'außerdem' only says that an additional piece of information is coming. It does not matter whether it is the second, third, or fifth point. 'drittens' is used only when you are clearly naming the third point in an ordered list. Learners may confuse the words because both often appear at the beginning of a sentence and connect arguments. The important point is: 'außerdem' is general, while 'drittens' belongs to a sequence with 'erstens' and 'zweitens'.
drittens
Drittens müssen wir klären, wer vor dem Termin die Unterlagen mitbringt.
Thirdly, we need to clarify who will bring the documents before the appointment.
außerdem
