In short
Fish For Singles' guide to messaging problems on dating sites: the usual reasons you can't message someone are that messaging needs a paid membership, their filters leave you out, they've blocked you or closed their profile, or your new account has limits while it's checked. If you blocked someone yourself, unblock them from your settings.
| Most common reason | Messaging is a paid feature on many sites |
|---|---|
| Their filters | Age or distance settings can leave you out |
| Blocked or gone | The profile may vanish or the button may grey out |
| Unblocking | Usually under settings, in a blocked list |
| On Fish For Singles | Reading and replying to messages needs a paid membership |
You've found someone whose profile made you smile, you've written something you're quite pleased with, and the message won't send. Or the conversation you were enjoying has simply gone. Before you decide it's something you did, it's worth knowing how often the reason is a setting or a membership rather than a person.
This applies to most dating sites and apps. Fish For Singles can't see or change anything on another service, but the reasons are much the same everywhere.
Messaging may be a paid feature
On many dating sites, joining, building a profile and browsing are free, but sending or replying to messages needs a paid membership. If you see a prompt to upgrade when you press send, that's what's happening. It isn't a fault, and it isn't about the person you're writing to.
Before paying, check how the membership renews and how to cancel. Our guide to cancelling a dating subscription explains what to look for.
Their settings leave you out
People set filters for age, distance and sometimes other things. If you're outside the range they've chosen, some sites won't let you message them, or won't show them your message. It isn't a judgement of you, just a slider somebody set months ago.
Our guide to age range settings explains how these filters work, and why a few years either way can matter.
They've blocked you or closed their profile
If a profile vanishes from your searches, your conversation disappears, or the message button stops working, the person may have blocked you or closed their account. Most sites deliberately don't say which, to protect everyone's privacy.
It stings, but it's part of dating again for everyone. People close profiles because they've met someone, need a break, or simply weren't ready. Please don't try to find them another way. Let it go, and give your attention to people who are glad to hear from you.
New account or message limits
Some sites limit what new accounts can do for a short while, to stop fake profiles and scammers. Others hold back early messages that contain phone numbers, email addresses or links, for the same reason. If your message didn't send:
- take out any number, address or link and try again;
- if you're new, wait a little and check whether the site has asked you to confirm your email;
- check whether you've reached a daily limit, if the site has one.
How to unblock someone
If you blocked someone yourself and want to undo it:
- Open settings or privacy.
- Find the list of blocked members.
- Choose the person and unblock them.
On some apps blocking can't be undone, and you'd have to wait for them to find you again. Unblocking doesn't send a notification, so they won't know unless you write.
When to report rather than reply
Sometimes the problem is the other way round: someone keeps messaging you after you've said no, asks for money, or pushes you to move to another app straight away. That's when to block and report, not reply. If someone asks you for money, stop contact and report it. In England, Wales and Northern Ireland that's Report Fraud; in Scotland, call Police Scotland on 101.

Questions people ask
How do I know if someone has blocked me on a dating site?
Most sites don't tell you directly. Signs include their profile disappearing from your searches, your conversation vanishing, or the message button no longer working. A closed account looks the same, so you can't be sure, and it's best not to try to find out another way.
How do I unblock someone on a dating app?
Look in settings or privacy for a list of blocked members, choose the person and unblock them. On some apps blocking is permanent and can't be undone. Unblocking doesn't send them a message, so they won't know unless you write.
Why does it say I need to upgrade to send a message?
On many dating sites, sending or replying to messages is a paid feature, while joining and browsing are free. That's the case on Fish For Singles, where reading and replying to messages needs a paid membership.
Why did my message not go through?
Some sites hold back messages that contain phone numbers, links or email addresses in the first few messages, to protect members from scams. Remove those and try again. If you're new, your account may also be limited while it's checked.
Can Fish For Singles fix messaging on another dating app?
No. Fish For Singles is a separate website and can't see or change anything on other dating sites or apps. For a problem with another service, use its own help pages.
