const message = { To: "me", From: "you" };
const templateMessage = { ...message, TemplateId: "1" };
const filter = { offset: 0 };
const editSender = { Color: "black" };
const templateValidator = {
    Subject: "123",
    HtmlBody: "123345",
    TextBody: "123535"
};

declare const error: postmark.PostmarkError;

declare function callback(err: any, data: any): undefined;

const client = new postmark.Client("124345", options);
const adminClient = new postmark.AdminClient("1123235", options);

client.send(message, callback);
client.sendEmailWithTemplate(templateMessage, callback);
client.batch([message, message], callback);
client.sendEmail(message, callback);
client.sendEmailBatch([message, message], callback);
client.getDeliveryStatistics(callback);

client.getBounce(1, callback);
client.getBounceDump(1, callback);
client.activateBounce(1, callback);
client.getBounceTags(callback);
