When setting up your blog it is important to have your contact details on a contact page. I am surprised when I still find find blogs that have no contact details at all. You never know who is reading, and you might get he offer of a lifetime, only to have it pass by because you had no contact details. So, make sure you have a contact of some form, even if it is just your free email account.
The most logical place to put your contact details is on a contact page, such as www.travelbloggersguide.com/contact/. Most people will look there, or on your about page as well.
When publishing your email make sure not to publish your whole email address. This is how spammers find email addresses. There are evil spam robots that crawl the web harvesting email addresses. To avoid being “harvested” you can format your email like this:
travelbloggersguide [at] gmail [dot] com.
If you prefer, you can use an image link to display your email address.
[This email address image was generated at E-Mail Icon Generator]
This rule applies anywhere public on the internet. Never leave your email on places that can be viewed in public, such as forums or your Facebook account.
Contact Form Plugins
A contact form is another way method of contact through a blog. With a form you can customize the text input box, and your email is hidden from view.
