Sending mail by email: frequently asked questions
Can I tell paperplane exactly what to write?
Yes. Say “send this exactly as written” and give the words. They go through unchanged, and the quote shows them so you can check before you reply yes. If you would rather paperplane write it, give a direction like “a firm but polite note asking for my deposit back” and you see the draft first. Either way the approved words are locked to the quote.
Can I send a notecard or a postcard by email?
Not yet. Sending by email is letters, First-Class, at $0.99. Notecards ($1.99, or $2.99 with a real pen) and postcards (from $0.99) are on the web sender and in any connected agent, at the same prices.
What stops paperplane from mailing the wrong letter?
The quote. A yes only counts for the quote it answers: the exact recipient, words, class and price it was made for. Change a word or an address and the old quote no longer applies, so you get a new one. The address is checked against USPS data before any charge.
Can paperplane send a letter without asking me?
No. Every send starts with a quote, and nothing prints until you reply yes to it. A quote holds for 30 minutes and answers to one reply, so an old yes cannot send a new letter.
How much does it cost to mail a letter by email?
$0.99 for a one-page First-Class letter, postage and printing included. The quote shows the exact total before anything is sent. Certified Mail is $12.99 on the web sender.
