Micro Mailing Canada
Lettermail Mailing Services for GTA Businesses
Lettermail is Canada Post's service for addressed letters, invoices, statements and other correspondence mailed within Canada. Micro Mailing Canada collates, addresses and prepares Lettermail for GTA businesses so it moves through Canada Post's network without delay. Anything that meets Canada Post's acceptance conditions can be mailed at Lettermail prices, whether it is a single letter or an ongoing billing cycle.
What Is Lettermail, and What Can You Send With It
Lettermail is the most cost-effective way to send addressed personal messages, business correspondence, invoices and billing statements within Canada. It sits alongside other Canada Post direct mail formats, but Lettermail specifically covers individually addressed items rather than mass-distributed flyers or catalogues.
Lettermail can be anything a person or business chooses to mail at Lettermail prices, as long as it meets the conditions and requirements for acceptance as defined by Canada Post. Those rules and specifications cover envelope construction, addressing and content, and they determine whether a piece qualifies as Standard, Non-standard or Over-sized Lettermail.
What We Collate, Address and Prepare
Micro Mailing Canada has assisted many businesses in collating, addressing and preparation of Lettermail to ensure timely processing and delivery. For transactional documents such as invoices and statements, this often means pairing the invoice, statement and notice mailing run with the addressing step so nothing has to be handled twice.
Before a run goes out, we handle addressing and labelling and, where a piece needs a corrected or standardized address, inkjetting and address correction so it reaches Canada Post's system in a format that will not be rejected or delayed at sortation.
Standard Lettermail
Up to 245 mm long and 156 mm high, 50 g or less, with the correct postal code.
Non-standard Lettermail
Smaller than Standard's minimum size, up to 500 g, and outside the other Standard criteria.
Over-sized Lettermail
Exceeds Standard's size or thickness, up to 380 mm by 270 mm, and up to 500 g.
Lettermail Sizes and Dimensions
Canada Post recognizes three Lettermail size categories, and getting the category right affects acceptance. Standard mail has a maximum length of 245 mm and a maximum height of 156 mm, weighs 50 g or less, carries the correct postal code, and meets the criteria for Standard Lettermail.
Non-standard Lettermail is smaller than the minimum size allowed for Standard mail, can weigh up to 500 g, and does not meet the other Standard criteria.
Over-sized Lettermail exceeds the size or thickness of Standard items, up to a maximum length of 380 mm and a maximum height of 270 mm, with a maximum weight of 500 g. Knowing which category a piece falls into before printing avoids reprinting envelopes or inserts afterward.
Getting More From a Lettermail Campaign
We can help you get the most out of your Lettermail campaign in Canada by providing recommendations on best practices to save you money and reach your campaign goals. That starts at the planning stage, before formats and quantities are locked in, since early choices affect which size category a piece falls into.
If the goal is promotion rather than correspondence, Personalized Mail (formerly Addressed Admail) is usually the better fit, since it is built for marketing distribution rather than individually addressed letters and statements; our broader mailing services cover both formats under one roof. See Personalized Mail for how that product differs.
Whatever the volume, let us know the format and quantity so we can confirm which size category applies before anything goes to print, rather than after envelopes or inserts have already been produced.

Frequently asked questions
What is the difference between Lettermail and Personalized Mail?
Lettermail is built for one-to-one, addressed correspondence such as invoices, statements, notices and letters. Personalized Mail is Canada Post's product for addressed marketing campaigns; it uses similar addressing but is designed for promotional volume rather than transactional mail. Which one you need depends on whether the piece is a business record or a marketing offer.
Can Lettermail be used for marketing pieces, or only for correspondence?
Lettermail can be anything a person or business chooses to mail at Lettermail prices, provided it meets Canada Post's acceptance conditions, so a marketing letter is not automatically excluded. In practice, campaigns sent in volume are often better served by a dedicated marketing format, so confirming the right fit before printing avoids reprinting inserts later.
What size and weight limits apply to Lettermail?
Lettermail falls into three categories. Standard mail is up to 245 mm long and 156 mm high and weighs 50 g or less. Non-standard mail is smaller than Standard's minimum size and can weigh up to 500 g. Over-sized mail exceeds Standard's size or thickness, up to 380 mm by 270 mm, with a maximum weight of 500 g.
Can Micro Mailing Canada handle the addressing and preparation for us?
Yes. We collate, address and prepare Lettermail so it moves through Canada Post's system on time, including matching addresses to the correct format and correcting or standardizing addresses where needed. This is the same preparation many GTA businesses already rely on us for rather than handling it in-house.
What kinds of documents are typically sent as Lettermail?
Common examples include receipts or invoices, letters, post cards, notices, reports, financial statements, and product or service information. Anything that is individually addressed and meets Canada Post's Lettermail conditions can generally be sent this way, whether it is a single letter or part of an ongoing billing and statement cycle.
How do I find out which Lettermail category my mailing falls into?
The category depends on the finished size, weight and format of the piece: Standard, Non-standard and Over-sized are the three options, each with its own size and weight limits. For a mailing-specific answer, request a quote and we will confirm the category before anything goes to print.
Does Lettermail need to meet any Canada Post approval requirements before I mail it?
Lettermail must meet Canada Post's conditions and requirements for acceptance, covering size, weight, addressing and content. Pieces that fall outside those rules may be redirected to a different postal product or delayed at sortation, which is why confirming the category before printing is worthwhile.
