Why a countdown before sending?
This small delay isn't slowness: it's what keeps the service free and open.
A short delay comes before confirmation. It prevents accidental sends and limits abuse, which is what keeps the service free and open to everyone.
A brief countdown separates confirmation from the actual departure of the message. It regulates the pace of sends and makes automated use of the free service much harder.
The answer in detail
Without a delay, a script could fire off hundreds of messages in a few seconds — the door open to spam. The countdown imposes a human pace and makes such bursts impractical.
For a legitimate send, the impact is minimal: a few seconds of waiting, enough time to reread your message. It's the very reasonable price of a service that stays free for everyone.
This mechanism adds to other anti-abuse safeguards. The goal is constant: preserve the service's free and open nature without turning it into a tool for mass nuisance.
Concrete examples
›Reread before it goes out
The countdown gives you time to fix a typo or a number before it departs.
›Block the bots
An automated send in a loop runs into this delay and can't saturate the gateway.
Takeaway
A short delay that curbs abuse and preserves the free service, without hindering a normal send.
