There is no specific time to send a condolence message. However, avoid very busy times for the recipient, such as just before or during the funeral.
A condolence message can be sent in whatever way suits you best, whether it's by calling the person, sending flowers with a note, by email, or by text message.
And you can use several methods, such as sending a text and sending flowers during the funeral ceremony.
The most appropriate method will be the one through which you usually communicate with this person.
Generally, text messages are suitable:
if it is your natural way of communicating with this person
if you are not very close but still want to express your support
if you do not want to disturb the person, if it is still too early for a call, but you will still call the person later when the emotion has subsided a bit
If you are close to the person, add personal details to your message, such as good memories with the deceased, or even a photo of a good time with the deceased.
If you are not very close to the person, opt for simplicity. It's the gesture that counts, and your support will be appreciated.
