Print the letters on #10 envelopes, labels or window slips, add a Forever stamp, and mail them.
When you print, PigeonTrail marks each order shipped on Mana Pool with the link to its tracking page.
Mana Pool sets one shipping schedule for every seller, so the rules are short. These are the ones that matter for envelopes, quoted or summarized from Mana Pool's own help center with the date each page was last updated.
Under $60, an order of 1 to 14 cards ships as a letter, and the buyer pays $1.35 for shipping. From 15 cards it ships tracked in a bubble mailer, and from $60 shipping is free and tracked.
Mana Pool shipping rates, read October 19, 2026“Sellers cannot use letter tracking services such as TCGTracking or EasyPost to meet the tracking requirement. Letter tracking can only be used when tracking is not required.”
Shipping, Rates and Methods, updated September 20, 2026A letter order goes in a #10 envelope, with the cards in a soft sleeve, a top loader and a team bag, one of each for 7 or fewer cards and two of each for 8 or more, and the tri folded packing slip wrapped around them.
Recommended Packing Process for USPS First-Class Envelope, updated September 20, 2026“Typically, packages with 5 or more cards will need the Extra Ounce postage”, so weigh them or add the extra ounce stamp, since short postage can be charged to the buyer or sent back.
Make sure to use the correct postage for letters over 1 oz, updated September 20, 2026Mana Pool asks sellers to ship within 2 business days of the order, and its tips page suggests dropping letter orders in a blue collection box rather than mailing them from home.
Recommended Packing Process, and Tips on avoiding delivery issues, updated September 20, 2026Fully rigid envelopes, oversized envelopes, box grade cardboard inside an envelope, tape directly on a card, and clear tape on the outside are on its list of what not to use.
Shipping Materials and Practices to Consider, updated September 20, 2026Because Mana Pool counts only carrier tracking on its tracked orders, PigeonTrail leaves those orders out of your letters and tells you they need a package label. The letter barcode is for the 1 to 14 card orders that go untracked under Mana Pool's rules, where seeing the letter move still saves you a lot of questions.
Every letter has its own tracking page with your shop's logo and colors, the route on a map and the day USPS expects it. PigeonTrail gives Mana Pool that link when it marks the order shipped. If a letter runs more than a day past USPS's date, or goes five days without a scan, it is flagged in your list, and on Pro we email you about it.
On Mana Pool, open your seller dashboard, go to Integrations, choose Mana Pool API and create an API key, answering No to the inventory question. Then enter your Mana Pool email and that key on PigeonTrail's Connections page. We check the key with Mana Pool before saving it, and we keep it sealed.
Orders the buyer paid to ship as a First Class letter. Orders where the buyer paid for tracked shipping stay out of your letters with a note that they need a package label, because Mana Pool says letter tracking cannot meet its tracking requirement.
When you print, PigeonTrail marks the order shipped on Mana Pool with the link to the letter's tracking page, so Mana Pool has the link for your buyer. Mana Pool does not share buyer email addresses, so PigeonTrail sends these buyers no emails of its own.
Yes, any time from Connections. Disconnecting removes the webhook from your Mana Pool account and deletes the key we stored.
