What happens in the 48 hours before a seal breaks
From the heads-up to the tap on the seal: what your prospect sees, and what you see, while a letter is on its way.
A SnailReach letter does not arrive the moment you finish writing it. There is a short wait between sealing it and delivery, and that wait does real work. Here is what happens on both sides while a letter is on its way.
You seal it
When you seal and schedule a letter, you pick the weekday morning it should land, in your prospect's time zone. From then on the letter is locked. You can still cancel it before it arrives, but the words are set.
Before it seals, SnailReach checks a few things for you: that the address has not opted out, and whether a teammate wrote to the same person in the last week while their letter is still sealed. If either is true, you will hear about it before anything is sent.
They get a heads-up
Right away, your prospect gets a short heads-up email from your own mailbox. It tells them a letter is on its way from you, and when it will arrive. It does not give away what is inside, and it has no links at all, so it reads like a note from a person and not a campaign.
This is the part that feels different from cold email. Instead of one more message demanding attention now, they get a small, low-pressure note about something coming later. Many people are simply curious.
If they would rather not receive it, they can reply "no letters" to the heads-up. You mark it in SnailReach, the letter is cancelled, and nobody on your team can write to them again. Once the letter arrives, "Don't send me letters" is one click on the letter page.
The wait
In the day or two that follows, nothing else is sent. There is no reminder, no bump, no second email. That quiet is deliberate. The heads-up already did its job, and adding more would turn a letter into a sequence.
On your side, the letter shows as scheduled with a countdown to delivery. If they reply to the heads-up in the meantime, that reply lands in your inbox like any other email.
What you can do while you wait
Very little, and that is the point. But a few small things help the letter land well.
- Check your calendar has open times on delivery day and the day after.
- Make sure your booking link works and shows the right meeting length.
- If a teammate is also talking to the account, let them know a letter is coming.
- Resist the urge to send anything else in the meantime.
If something changes before delivery, like the person leaving the company or the news you wrote about turning out to be wrong, cancel the letter. A letter that has not arrived yet can still be taken back.
Why the wait helps
Most outreach competes for attention in the moment it arrives. A letter gets a second chance. The heads-up plants the idea, the wait lets curiosity build a little, and by delivery morning your prospect has already half decided to look. The letter arrives as something expected, not something to sort.
Delivery morning
On the morning you picked, the letter arrives by email from your mailbox. Inside is a sealed envelope with your company's brand on it. Nothing is counted as opened yet, because nobody has opened anything.
The tap
The open is your prospect tapping the seal. That is the one moment SnailReach treats as an open (no pixels involved), and it is the only one that triggers anything. You get an alert that the seal broke, with one follow-up written and ready to send from your mailbox.
Read it, change a word if you like, and tap Send. If they have already replied or booked, skip it. If the seal stays closed, nothing goes out on its own. Instead you will see a nudge you can send or skip.
Most of what makes a letter work happens before anyone opens it.
