How to prepare your mail – step-by-step instructions

To prepare your machineable mail:

  1. Choose the right container – lettertainers and letterflatainers (LFTs) for standard mail items, and flats tubs for oversize mail items.
  2. Place the mail properly in containers – it helps our automated equipment function smoothly.
  3. Label the containers – it ensures that mail items are directed to the appropriate location within our facilities.
  4. Make up monotainer and pallet – they make it easier to move the mail.
  5. Deposit the mail – at an approved site with required documentation.

See the Mail Preparation and Presortation Guide for Machineable Mail for a more detailed description of these steps.

To prepare your presorted mail:

  1. Sequence the mail – the presortation software will generate address labels in order by Postal Codes, delivery mode codes and alphanumeric sequencing.
  2. Group the mail – this involves segregating the mail, including labelling for some groupings.
  3. Place the groupings in containers – arrange the items in the containers so they face the same way.
  4. Label the containers – it allows us to direct mail to the right place within our facilities and/or a downstream destination.
  5. Make up monotainers and pallets – they make it easier to move the mail and maintain the integrity of the presortation.
  6. Prepare the Mailing Summary – it provides the details about your mailing, such as the software used to perform the presortation and how many containers your mailing has.
  7. Deposit the mail.

See the Mail Preparation and Presortation Guide for Presorted Mail for a more detailed description of these steps.

Tips for success

Get more value from the envelope
If you're already sending a letter or a bill, why not throw in a flyer, a newsletter or some other piece of sales information? If it weighs less than 30 grams, it won't cost extra.

Folding = Savings
If you're using an oversized envelope, consider folding the items you're mailing and fitting them into a standard # 10 envelope. This simple step can cut your postage costs by more than half.

Think of your envelope as ad space
Design your envelope with your customers in mind. Advertising messages, logos and attention-grabbing graphics all serve to make a striking first impression. If you use a postage meter, your message can also be incorporated into your meter impression.

Boost response with return envelopes
Make it as easy as possible for your customers to get in touch with you. Include a prepaid response vehicle, like a pre-addressed stamped envelope or Business Reply Mail™ card.

Get it right the first time
The fastest way for us to deliver your Incentive Lettermail items is to sort them with our high-speed machines. To help us do this, make sure your mail is properly addressed, and that you have the correct Postal Code. Check our Addressing Guidelines to learn the most efficient way to address your mail.

Machines don't like staples
Not only are staples on the outside of an envelope potentially dangerous for people handling your mail, they can slow down delivery time.
