Adverb is a word than modifies a verb.

In your sentence, "She responded professionally to the e-mail" responded is the verb. 

Read the sentence, what modifies the verb? 
She responded. -> How did she responded? 
She responded PROFESSIONALLY. 

Professionally modifies responded, thus the word 'professionally' must be the adverb.

Almost always words ending in "-ly" are adverbs. [Exceptions include fly, ply, etc.]
