# Snap packs A snap pack is a pressure-sealed mailer with perforated sides for easy opening. Snap pack mailers are versatile and can be used by a wide range of industries including Financial Services, Education, and Healthcare. The official-looking nature of snap packs demands attention, offers unique tactile engagement, and has one of the highest open rates among mail types. To get started with snap packs, check out our [API documentation](https://docs.lob.com/#tag/Snap-Packs),[ ](https://github.com/lob/examples/)or[ Template Gallery](https://www.lob.com/template-gallery#letters) for inspiration. {% hint style="info" %} Snap packs are exclusive to Enterprise edition customers. Upgrade your [Print & Mail edition](https://dashboard.lob.com/#/settings/editions) to gain access to this mail format, or reach out to our [sales team](https://www.lob.com/sales) to learn more. {% endhint %} {% hint style="success" %} Snap packs currently have a 4-day SLA. {% endhint %} ## Layout dimensions & specs ### Layout dimensions Lob’s snap pack offering has a flat, final trim size of 8.5x11”, a folded (in half) dimension of 8.5x5.5", and three perforated sides. Snaps packs are printed double-sided in black and white or color. Reference our design templates on where to place your design elements; carefully note the location of the address block and other ink-free zones. * [8.5x11” snap pack template](https://s3.us-west-2.amazonaws.com/public.lob.com/assets/8.5x11_Snappack_template_address.pdf) Snap packs DO NOT need additional trim space added to their dimensions because their production journey does not involve trimming (the way a postcard would). Please set your document sizing to the above dimensions when submitting to Lob. {% hint style="warning" %} **Make sure all artwork submissions are facing upright for both inside and outside panels**. Our printers will invert the inside panel of submitted customer artwork during the production phase. {% endhint %} ### Paper specs We use a few pre-approved papers across our commercial printer network. In ensuring uniform quality and consistency across all of our mail pieces, each paper source specification must fall within a small range. The specification/value range pairs are: * 8.5 x 11" B\&W & color snap packs * Basis Weight: 80# text * Bi-fold ### Ink-free zone dimensions 8.5x11" snap packs: * ½” around the entire flat piece (for perforation) ## Snap pack best practices Ensure your snap pack self-mailers get to their final destination by following these guidelines: * The `from` field is required for all self-mailers, regardless of the destination * Snap pack should not contain any PII outside of the [no-ink zone](https://help.lob.com/print-and-mail/designing-mail-creatives/artboard-layout#address-block-postage-8) * Avoid any [prohibited artwork](https://help.lob.com/print-and-mail/designing-mail-creatives/artboard-layout#prohibited-artwork-11) to ensure your mail does not get rejected by USPS * HIPAA-compliant snap packs are offered at this time, so long as all HIPAA related information is on the inside of the snap pack. * [Mailing Class](https://help.lob.com/print-and-mail/building-a-mail-strategy/mailing-class-and-postage#available-mailing-class-options-5) options may differ based on destination and use type (e.g. promotional vs non-promotional) * We do not recommend placing promotional address information in your creative in the bottom 2.375" of a mailpiece _opposite the address panel_. This will prevent the USPS from accidentally scanning the wrong side of the mailpiece. [Learn more here. ](../../artboard-layout#address-zone-warning)
