It depends on the client and their preferences.  

Whatever is the most comfortable format for them. I am an iPad junkie so email is fast way to reach Mel 

It really depends on what the client likes.  Though my preference is a personal call.

Personally, I prefer email but it really depends on the customer.  Some of mine do not have a computer or are not that comfortable with it so calling is best.  

I usually respond in the method they contacted me as their prefered method, when confirming appointments or anything that could be miscomunicated I make sure its not just verbal, prefer text or email for papertrail.

I prefer phone, but I use email for proposals and text sometimes for quick follow up q's and simple items.

I prefer email as it is easy to access and also I can categorize the emails.

Calls, emails and texts.

Dipti nailed this one!

The way 'they' want.

Whatever they like - you know how I work!

I'll ask them how they prefer to communicate. Anymore, it's:

1. texing
2. phone calling
3. emailing

Totally out: faxing 

Calls, email, text... it depends on the client and how they prefer to communicate. But if it's items relating to contracts, I want emails so I can save the flow of communication in the file.

It is not my preferred, it is their preferred way of communicating.

Praful Thakkar from the day I start working with a client, I ask THEIR preferred method of communication, and notate it in their folder.    I have all their numbers and emails, but communicate they way they would prefer.

A combination of emails and phone calls always worked for me.

I use Facebook.

When I teach workshops on social media I ask agents if they remember a time when they would ask leads "what is the best way to contact you phone or email?" Then came "... phone, email, or text?" pretty soon agents will say "are you on Twitter? I'll tweet you more information about any listings that come up, would that be alright?" 

This is a great way to brand yourself online, because Twitter is not only sent to your clients it is also viewed by their followers too. This increases your online reach and can be a great tool for your future brand. 

Any method is fine with me as long as it's consistent. Communication can be diminished by using too many sources and sometimes this may be intentional. Email is my preference from an organizational standpoint.   

I prefer email because it is trackable and we can always refer back to it if there seems to be any confusion about a particular topic.

Most clients prefer text messages so I  am forced to text. I prefer emails. 

I prefer telephone, but I always am willing to accomodate my clients.

Praful Thakkar Text is getting more and more popular with my folks. email a second method, and phone reserved when real interaction needs to occur or it's very important.
