What type of consent should I get from the recipient of my message?
The law generally requires express consent. This type of consent requires identifying the purpose for why consent is being requested and must identify who is seeking consent. This consent may not involve pre-checked boxes, rather there must be an express, opt-in by the user. Express consent can be obtained verbally, but it will be harder to prove verbal consent if there are any challenges.
