As communications methods evolve, it seems pointless for notice clauses in contracts to specify the means by which notices must be sent. (Not that long ago, I saw a notices provision listing telexes as one of the permissible methods.)
The sample notice clauses focus instead on making sure that a notice is in fact received or refused. The sender of a notice, knowing that she might someday have the burden of proving up receipt or refusal, can choose whatever transmission method she deems appropriate.
- In some routine situations, a party sending a notice might be comfortable transmitting it via email with an automatic return receipt.
- In more-consequential circumstances, the party sending the notice might decide to go with FedEx, or certified mail, return receipt requested, delivery restricted to addressee, so as to have third-party evidence of successful delivery.
