If you're unsure about which card to select, it can be helpful to ask a coworker or supervisor for advice. Timing is also an important factor when sending a sympathy card. Ideally, you should send it as soon as you hear about the recipient's loss. Doing so demonstrates that you're thinking of them and are ready to offer support during this challenging time.
