Q: Should I use a postage meter?

A: The answer to this question depends on the volume, frequency and current cost of sending mail.  You also should think about the additional costs associated with a postage meter such as the rental fee, maintenance fee and mailing supply costs. Another thing to keep in mind is who will be sending mail for your company? Will it be multiple people? Just one? Do they work from home on occasion? If you have multiple people who need a postage meter and they are working from home then you’ll need multiple postage meters. So while we can’t tell you if you should get a postage meter or not we encourage you to look at all the factors to decide if a postage meter will save you money or cause you more hassle.

Q: Does USPS sell postage meters?

A: In order to obtain a postage meter you will need to either rent or lease one from a dealer. The USPS authorizes only a few companies to manufacture and supply postage meters and you’ll have to pay a monthly fee to utilize the meter.  Fees will range depending on the features and services you decide to go with. Also, monthly fees typically do not include the cost of maintenance for fixing any issues that may arise with the meter. While postage meters can become a lot to manage, with Switch you don’t need to worry about that. There is no need to rent a postage meter or purchase mailing supplies when you send mail via Switch.

Q: What is the difference between first class and standard mail?

A: The mail differences between first class and standard mail have to do with price, speed and type of mail being sent. First class mail is typically delivered in 2-3 business days and is used for personal or business mail. Standard mail is typically reserved for advertisements or mass mailing campaigns. It’s much cheaper than first class mail but there is no delivery guarantee date and takes longer to deliver than first class mail.  Switch supports First Class Mail.
