Advice on next steps

[Griffin Fehrs]

Greetings everyone!

So, 5 weeks ago I sent out approx. 800 mailers. I built an absentee owner list using listsource. The first mailer I sent was a postcard used from vistaprint.

My criteria looked as such:
County
CT:HARTFORD
CT:MIDDLESEX
CT:NEW HAVEN
(First) Mortgage Origination Date
01/01/1900-08/01/2005
Last Market Recording Date
01/01/1900-01/01/2005
Property Type
Residential: Duplex
Residential: Multi-Family
Residential: SFR
Equity(%)
40 to 100 %
Last Market Sale Price
$50,000-$125,000
OWNER-OCCUPIED
Absentee Owned In-State
Absentee Owned Out-of-State
ALL STATES
ADDRESS-COMPLETENESS
Mailing and Property address Complete
CORPORATE-OWNED
Exclude

Out of all the mailers, I have only received one response. Considering this disappointing return, I am wondering what possible errors I may have made.

As it is coming time for me to send out the 2nd mailer, what would be the best approach? A letter? another postcard?

Thanks

Griffin
