Emails
Email has the value of expediency.
If there is a deadline for a decision, emails up to the eleventh-hour can be extremely effective and impactful. They can be coordinated to come in waves if needed.
However, that advantage is also a drawback.
Email is especially common now because it is so easy to send and receive. An official's public mailbox may become full of various competing emails or messages, and they are easier to ignore or turn into a basic count of volume. See a sample email message.
Mailed letters require someone to physically handle them, open them, read them and catalog them. The very fact that they require that level of time and effort of receive makes them powerful. They are very bad, however if time is of the essence.
Do you send an email or find a pen and paper?
