As the postal strike holds the national delivery service in a stranglehold, advice is being given from consumer rights groups.
People concerned about getting an important or special letter are being told to consider alternatives to the Royal Mail.
Speaking on the advice from Consumer Focus, a BBC report cites DHL and City Link as companies who can keep your mail moving.
Postal alternatives like Parcel2Go can cope with the delivery demand of individuals and businesses and aren't affected by the strike.
