Professional letter openers and post-processing equipment for high-volume mailrooms.

Postmark builds high-volume automatic letter openers for mailrooms that process thousands of items a day — bureau service providers, banks, utilities, local government and anyone handling remittance mail.

These are production mail machines rather than desktop openers: they feed, open and stack continuously, and are specified by throughput and envelope mix.

What we stock

The range covers the 3056, 3068 and 3078 automatic letter openers, plus the MTF2 mixed thickness feeder for mail streams where envelope thickness varies from single sheets to bulky contents.

How to choose

Daily volume — Specify against your peak day, not your average, or the machine becomes the bottleneck at month end.
Envelope mix — If thickness varies widely across your mail, the mixed thickness feeder is what keeps the machine running without jams.
Contents protection — Cutting depth matters when envelopes hold checks or documents that must not be damaged.
Downstream handling — Consider how opened mail is stacked and moved to the extraction stage.

Frequently asked questions

How many envelopes an hour can these machines open?

Throughput varies by model and envelope mix. Each product page lists the rated speed; tell us your daily volumes and we will point you at the right model.

What does the mixed thickness feeder do?

The MTF2 lets the machine feed envelopes of varying thickness in the same run, rather than requiring mail to be pre-sorted by bulk. It is the usual fix for jam rates in mixed inbound mail.

Will it damage checks or documents inside?

These openers take a very thin trim from the envelope edge with adjustable depth, which is precisely what protects the contents. Set the depth for your envelope stock during commissioning.
