If the other party still has stamps to read the letter for free, the letter you sent can be read by the other party. If the other party doesn't have a stamp, you must put a stamp on it if you want the other party to see your letter. Of course, you need to pay for this stamp. If one person sends it to the other party many times and you only have one free stamp, then you can send it to one person all the time instead of using stamps every time. You can see some letters that say "free reading" at the back. One reason may be your Jiayuan stamp, and the other reason may be that the other party has ordered a monthly letter. Some letters are followed by the word "read", indicating that they cannot be read. For one reason, you have run out of Jiayuan stamps, and the other party may look at them for a month. The reasons for this are as follows: First, if you apply for a monthly subscription, you can check your contacts' letters indefinitely during the service period. 2. If you apply for a monthly subscription, the recipient can read the letters you sent during the service period for free. The letters sent during the service period are first displayed on the list page of the recipient's mailbox, and a sign shows the words "free reading". 3. If you apply for diamond membership: (1) Send and receive all letters free of charge: read all letters free of charge during the service; Letters sent during the service are first displayed in the inbox of the other party, with signs in front, and contacts can read them for free. (2) Exquisite stationery breaks through the limit: when the other party reads the letter, it will see the exquisite and unique love stationery background; And you can break through the restriction of the other party's choice of friends, you can not meet the age and height requirements, and you can also send letters. (3) Highlighting identity: highlighting the avatar is more eye-catching; Have a beautiful profile page, more shiny; During the service period, you can also set whether to display your diamond membership on my jiayuan homepage.
