Thanks for reaching out. Unfortunately, I’m out of the office from [day/month] to [day/month] with limited/ no access to email. If your question can wait, I’ll be responding to any emails I miss when I return. If not, contact [Name] at [email] or [phone] and he/she will take care of your request.
You can use software like AppogeeHR to set up vacation emails that will automatically turn on when you go away for approved leave. You can also create templates of emails to share with your team with a tool like Right Inbox.

If the visitors land your website after business hours or during holidays and do not get any response they might slip away. They could be important sales leads and losing them can impact your business.
