where does the signature block go on a memorandum
- There are three required elements of the memo: 1  Title--The title typically consists of the company name and the word memorandum. 2  Heading Block--The heading block should be double spaced. Sign your initials by your name rather than including a signature at the end of the memo as you would in a letter. The subject line should be capitalized as if it where a title and should succinctly describe the topic of the message.
