How Many Stamps For A 4×7 Bubble Mailer

How Many Stamps For A 4 x7 Bubble MailerSending items in a 4×7 bubble mailer through the mail can be confusing when trying to determine the proper postage. Postage costs can vary greatly depending on several factors, leading to inconsistent quotes from the post office. This article will break down the key considerations for calculating postage for a 4×7 bubble mailer.

Bubble Mailer Dimensions

A standard 4×7 bubble mailer has maximum dimensions of 4 inches by 7 inches. Bubble mailers are designed to provide padding and protection for items being shipped while still fitting within certain size restrictions for USPS mail classes.

Weight of the Contents

The weight of the contents being shipped is a major factor in determining postage cost. There are set pricing tiers based on weight:

• 0-1 oz – Starting at $0.55 for letters up to $3.19 packages
• 1-3 oz – Starting at $0.71 for letters up to $3.19 for packages
• 3-6 oz – Starting at $0.92 for letters up to $3.51 for packages

Heavier items will cost more to ship. Most 4×7 bubble mailers with just a few small items inside will weigh less than 1 oz.

Type of Service

The USPS offers different classes of mail service with different rates:

• First Class Mail – Affordable without tracking. Best for lightweight letters and flats.
• First Class Package Service – Affordable with tracking. Best for lightweight packages up to 1 lb.
• Priority Mail – Faster with tracking. Used for packages up to 70 lbs.

First Class services are the most economical options for small, lightweight 4×7 bubble mailers. But Priority Mail provides faster delivery times and included tracking.

Automation Compatibility

The contents of the bubble mailer can affect its automation compatibility – meaning if it can be processed efficiently by USPS mail sorting machines. Rigid items like cards in toploaders make the mailer non-machinable, requiring extra handling. Using First Class mail options, non-machinable mailers incur an additional $0.25 fee.

Zone Classification

The distance a 4×7 bubble mailer is being shipped to will impact the postage rate. The US is divided into different postal zones ranging from 1-9 based on mileage. Further zones cost more to ship to. Online sellers can print zone-based postage using services like PayPal ShipNow and Pirateship.

Extra Services

Optional extras like certified mail, signature confirmation, and insurance can add cost. Most extras require using pricier Priority Mail. Certified mail provides proof of mailing and delivery status. Signature confirmation requires the recipient’s signature. Insurance covers package value in case of loss or damage.

Comparing USPS, UPS & FedEx

For lightweight 4×7 mailers, the USPS is substantially cheaper than other carriers like UPS and FedEx which focus more on package delivery. The USPS offers specialty mail classes optimized for envelopes and flats. Bubble mailers meeting certain criteria can ship via First Class options.
