Within twenty-four hours of a pledge or commitment made by telephone, CAPTEL mails a high quality, personalized letter in a closed-face envelope with a reply form and return envelope. Additional follow-up letters are sent as needed if pledge commitments remain unfulfilled. CAPTEL's in-house mail production facilities can produce over 10,000 letters per day.

For clients desiring fax or e-mail confirmation services, CAPTEL offers broadcast faxing and e-mail confirmations. Pledge or sales confirmations for more complex, time-sensitive projects will be e-mailed or faxed to clients upon completion of each call.
