Low-quality databases
According to SalesGravy, many business people and marketers care about quantity, but the quality of leads in a database is essential. Irrelevant leads, obsolete e-mail addresses and receptionists' and assistants' contact information won't make you successful.
Purchased databases
The quality of databases sold by companies vary, of course. Frequent problems that can occur with purchased databases are that they are obsolete, the leads are too “busy” and, therefore, they're less effective.
Too small
Quality does surpass quantity in importance, but with a database that is too small, you can't expect miracles.
No groups
If you don't divide the leads in a database into groups and subgroups, and you don't send these groups special e-mails, it means that they all get the same messages. As a result, these e-mails are so general that they have little chance of engaging prospects.
E-mails sent too often
You can't bother clients with your messages too often, otherwise they might unsubscribe from your newsletter. The rule of thumb is not to send more than one or two e-mails in one quarter.
