You can build forms with a variety of fields in them which are then emailed to you. Add a new block to a page, choose Contact Form as the block type and a form like the one below will be added to the page. You can then move it up and down the page as required like any other block.
Customising your Form
By clicking the cog icon on the form block you can make a large number of changes to the form. You can add lots of form elements and choose which ones are required for instance. This way you can change it from a simple Contact Us form to a fairly complex form requiring lots of details.
What happens when the form is submitted?
When a visitor to your site fills the form in the form information is emailed to the email address you have specified. To set this address go to Site Settings -> Site Emails. You can also add a CC address so that the form is copied to another person in your organisation.
By default, any form on your site will generate an email to your chosen email address which will contain the following text along with the form submission.
DO NOT REPLY TO THIS EMAIL - it won't be received by anyone.
The emails come from the address firstname.lastname@example.org which is not monitored and if you reply, perhaps because you think you're replying to the person who made the enquiry, your reply won't be read by anyone.
However, that seems to be a shame - after all, most forms you might create on your website would ask for the enquirer's email address, so it would be a good idea if when you replied to an email from email@example.com that the reply would actually go to the person who made the enquiry instead.
Luckily, the folk who designed email in the first place thought of that. We can provide a 'replyTo' header to the email which tells your mail client to actually send the reply to the enquirer's email address, not to firstname.lastname@example.org.
So why don't you do that?
Well, unfortunately over the years we've learned that not all email clients treat the replyTo header in the way they should. Some, (and I'm looking at you here, Samsung phones!) don't, so even if we send the mail with a replyTo address, if you use a Samsung phone the reply will go to email@example.com and get lost, even though you'll believe you've replied correctly to the enquirer. This is a worse situation than us having to tell you "Do not reply to this email" because you won't understand why you're not hearing back from your customer/enquirer.
Changing the default
If you are certain that neither you nor anyone else who responds to contact forms on your site has a Samsung phone, then you can change the default behaviour in Dashboard -> Site Settings -> Site Emails. If you do so the words "Do not reply to this email" won't be added to the emails you recieve, and the replyTo address will be added as a header.
However, note that the replyTo address will only be added to the emails you receive if a field with the name 'email_address' or 'email' exists in the form, and the enquirer has filled it in with a valid email address. By default when you create a new form it will include the field 'email_address'.
