When someone you love is in prison, a letter is one of the few ways to stay part of their day. It can be read more than once, kept, and shared with no one else. For many families it can become the steadiest link they have.
This guide explains, in plain terms, the official ways families can write to a loved one held by the Singapore Prison Service (SPS), what to get ready before you start, and what to expect after you send a letter. It ends with a short, separate note on how Lumera can help, if you would like support.
1. The official ways to write
There are two ways to write, and both go through the prison authority. Whichever you use, the prison decides whether and when your letter is passed on.
- SPS e-Letters: an online service on the official SPS website for writing to a person in SPS custody. The SPS e-Letters page explains who can use it, how to sign up or log in, and the current limits.
- Letters on paper: SPS's resources for families explain how families can keep in touch, including written mail. Follow the official instructions for the address and anything you plan to include, because items that do not meet the rules may not be passed on.
If you are not sure which route suits you, start with the SPS e-Letters page. It is the official, up-to-date description of the online service, and it links to the related SPS pages.
2. What to have ready
A little preparation saves time and avoids letters being held back for missing details.
- Your loved one's details as the prison has them. Their full name as it appears in official records, and any reference number you were given, are a good start. The official page lists exactly what is required.
- Your own details. Using e-Letters means identifying yourself to the service; the SPS page explains how to sign up or log in.
- Time. Every letter is checked before it is passed on, so it is better to write early for birthdays and other dates that matter.
- Something to say. It does not need to be long. A few honest lines about home can mean a great deal.
3. What happens after you send a letter
Prison mail is reviewed before it reaches the person it is written to. The review takes time, and the time can vary, so a letter may not arrive on the day you send it. SPS publishes current information about processing on its e-Letters page.
How your loved one can reply, and how you will find out that a reply has arrived, is also explained by SPS. If a reply matters to you, check regularly, so it does not sit unread.
If a letter does not seem to have arrived, contact SPS through the channels listed on its official pages. Only the prison can say what happened to a particular letter.
4. What you can write about
SPS decides what may be passed on, and its pages set out what is not allowed. Read them before you write. Letters that break the rules may be held back.
Within the rules, ordinary life is often the best material. Small, everyday news is what makes a letter feel like home:
- How the family is doing: children's school, a new job, a meal you cooked, a trip to the market.
- Things to look forward to, without promises you cannot keep.
- News, sport or a story you read, so they have something new to think about.
- Questions they can answer in their reply, which keeps the conversation going.
5. Tips for a letter that helps
- Write regularly. A short letter that arrives often can mean more than a long one that arrives rarely.
- Keep it simple and clear. Short paragraphs are easier to read, especially if the letter is printed or read in a second language.
- Put the date at the top, so your loved one can follow the order of your letters.
- Be warm and honest, and do not hide everything that is hard. At the same time, avoid sharing worries they can do nothing about from inside.
- Keep a copy, so you remember what you have already said.

How Lumera can help
Some families would rather have help with regular letters, especially when they live overseas, work long hours, or write in a different language. This is what Lumera does:
Curated letters, weekly or daily
Free members receive one curated letter a week. Lumera Plus members receive one letter a day, with content they choose (news, entertainment and sports, life stories, novels and more) and custom content requests for birthdays and other moments.
We write and check SPS mail for you
You don't need to register an SPS account, fill in the forms, or track the review process yourself. We write and send the letter on your behalf, and check for prison mail every day, whether you are overseas or in Singapore.
Translation
Lumera Plus members can have outgoing letters translated into their loved one's language, and replies translated back for them to read.

There is a Free plan and Lumera Plus. Current prices and details are in the FAQ.
