Interstellar communication

Scenario:

Earth men colonized a terraformed planet orbiting Alpha Centauri. There are already industries developed there, farms, mining etc. There's a large fleet of cargo ship capable of reaching 0.8C (over long distances - nuclear pulse propulsion) serving both systems (colonies both in our Solar system and the Alpha Centauri one).

Question:

What's the best way to establish communications between both systems with reliability of message delivery ?

• Assume current physics knowledge and tech.
• Messages might range from state courier, legal matters and commerce, cargo arrangements to personal messages, if possible.

• Particle entanglement allowed if you find a good excuse.

• EDIT - If you send a ship to deliver messages about commercial transactions, you might very well send the cargo with it, so there would be no point in sending messages.
