The certification letters are those which are accompanied by a certificate to a person. It is basically an information letter which contains the information of why and how come the person lands in the benefit of getting the certificate awarded to him or her.
These letters also serve as the acknowledgement letters for recognizing the efforts put in by the addressee of the letter in something which qualifies him or her to be worthy for getting the certificate which is enclosed along with the letter. The enclosure is usually obligatory for these letters and hence one should make it a point to mention about it in the letter.
For those which do not contain the enclosure but only the news of the certificate being awarded to the person, the date or the occasion on which the certificate will be handed over should be mentioned vividly in the certification letter. The next step is to express a hope that the person to whom the letter is addressed accepts the acknowledgement of his or her efforts in the certificated form.
The conclusions of these letters should include expression of hope and surety that the good work from the recipient of the certificate will continue and the acknowledgement will rain in again and again. The certificate letters should bring in the impression that the institution or the person awarding the certificate is happy and proud to do so and will be even more proud to do so in the future for prospective good deeds.
