5. Holiday Voicemail Greetings. Happy [X holiday]! You've reached [your name] at [X company]. I am currently out of the office, but please leave me your name, phone number, and the reason you are calling, and I’ll return your call after the holidays.
Ive been saving my grandmothers voicemails for almost 8 years now and when i went to upgrade my phone, i almost fainted when the rep told me they were going to be erased. Thanksfully he put us in touch with a company called http://www.voicemailsforever.com and they ended up much cheaper than the one you suggested above. i think your readers would benefit because they do it for so much less.

In Provide the caller with these options, select an option. Some options will prompt you for additional information, such as an alternate phone number or text to be read to the caller.
There's no single best way to craft an after hours greeting. The most important point is that you equip your customers with what they need to know, and give them an avenue to contact you, whether that's through voicemail, email, or other channels.
