> SPF and DKIM are neither necessary for mail delivery nor sufficient to assure delivery.
This statement, while true, is completely useless. Without SPF and DKIM email providers will view your emails with more suspicion, so that a larger percentage of your email ends up in spam even when it really isn't. SPF and DKIM do not guarantee delivery but they reduce the chance of your email being inappropriately recognized as spam.
