My experience is that it often depended on the recipient. You can get attention both ways. And it depends what it is you're mailing. On expireds I've done a mix of both.

Post cards for sold properties have definitely got me listings, but I use envelopes with (occasionally) hand written & labeled addresses monthly to my database. My e-report gets a 1-10 per month reply from my database too.

It's a "mutual fund' approach, I don't invest in any one "stock", I prefer the mixed approach monthly.

Hand-addressed envelopes.

Depends on the look of your postcard, if it looks like everyone else's it will make a trip to the trash can.  As far as a letter, if depends on your market place.  A

I would say a postcard because it is easy to read on the way to the trash can. If you put something of value on it, it might make it to the refrigerator door.

Post cards all the way and the big ones!

With expireds a letter has been working better for me.

Post cards with an eye-catching message.

Post cards with really relevant sales data that is something they would keep for future reference. How many seconds do we have for them to look at it and decide whether it is relevant to their lives or not? I have had listings that started with a postcard that was kept and a call to me months later. It works!

I like post cards because they can see the message and don't just throw out the envelope without being able to see your message

I would say postcards--they have a better chance of being read.  If an individual sees that it is a marketing piece it may not even get opened.  And the cost is much higher.

Generally post cards have higher response rate...less work/more likely to see it.

I do both during the year, in hopes they read one of them! 

Tony and Suzanne Marriott, Associate Brokers given a choice, I'll go with 'Mail-in-Envelopes'.

People can read the postcard - I mean trash it without reading the postcards (irrespective of the size!)

Postcards are quicker to send and quicker for your audience to read.

And less expensive.

But personally, I seldom read any snail mail unless someone calls it to my attention.

Postcards work best for me.

Mail in envelopes for me.

I'm goin with postcards, quicker for prospect to read.

Really, it depends on the recipient. I like postcards though.

Postcards have always edged out our letters by a fair amount. Mail campaigns require current & correct names and addresses so make it a habit to constantly monitor where and who receives your message. 

Envelopes for me. Postcards are usually tossed in trash immediately. 

postcards.... envelopes are easy to throw out without reading one word....the postcard will catch a glance and if it's eye catching, they'll read and save...

Content is what matters and if your content does not have a call to action message then neither will work very well

Good Question,  I say post card but now I am going to read all the answers!

For me:  Postcards with a simple message.   

It depends.  I'm more likely to see the postcard because it is right there, but a letter is more formal.

Postcards because they can toss them in a drawer and review the card easily....

  We sue both....depending on the messdage. Our purple enveloeps go out monthly to three spheres...and we scattr cards to tht groip and for other campaigns..

Used both for geographical general solicitation and postcards for just listed/just sold

Tony and Suzanne Marriott, Associate Brokers I send letters.

Postcards

I think the consensus is a blend depending on the message

It depends on what you are trying to communicate. Post cards are good for listings and sales.

Postcards. Big, glossy and striking.

They will prove equally successful. The art is making sure the 'What's in it for me?" headline resonates with what is on their mind.

Since less that 5% of the population of recipients are packing boxes, (you know the stats for your area)  the challenge to zero in on THEIR issues, not the masses, is essential.

I use postcards for areas above 5% and letters in high equity low turnover communities.

I have had equal response with both.  The address on the envelope is hand written.  Just got a listing this last week from an envelope that included market information.

Post cards..well executed with a good message.
