Send this first (for not replying)
A slow reply is rarely about the message and usually about avoidance, and they can tell.
I am sorry for the silence. I saw it, I meant to reply properly, and then I let it slide — which is worse.
A slow reply is rarely about the message and usually about avoidance, and they can tell. The apology works best when it is honest about that. What follows is written for exactly this — messages you can send to your school friend in the next few minutes, plus the part most advice skips: what to leave out.

The best sorry wish for a school friend for not replying is one that takes responsibility for a specific action, acknowledges the effect it had, and asks for nothing in return. Reply to the original thing first, then apologise for the delay. Apologising first and never addressing what they actually said repeats the exact behaviour you are apologising for. On BuildNectic you can also send a personalised sorry website — a private apology page that opens slowly instead of in a notification bar — your words paced line by line, your photos, and a folded paper letter they unfold themselves — which arrives as a single private link on WhatsApp and needs no app or account to open.

A different angle on the same first move, in case the first one is not how you speak.
You messaged me something that mattered and I left it sitting there. I am sorry. Answering it now.

I am sorry for taking so long. There is no reason that makes it okay, so I will skip to the part where I actually respond.
Written to be read slowly rather than glanced at in a notification.
I would rather be wrong and honest with you than right and distant from you. I was wrong. I am sorry, school friend.
Addresses the pattern, which is what they are actually waiting to hear.
I am sorry. I am not asking you to be okay yet. I just needed you to know that I know, and that I am not going to do it again.
Enough to restart things without forcing an immediate answer.
I am sorry. Not sorry that you are upset — sorry that I did it. I know exactly which part of that hurt and I am not going to pretend otherwise.
For the apologies that have to travel before you can.
I have been replaying it and there is no version where I come out reasonable. I was wrong, you were not, and I am sorry.
When the only thing left to add would be an excuse.
I am sorry. You deserved patience from me and I gave you the worst version of myself instead. That is on me, not on you and not on the day.
The one you would rather not send, which is usually the one that works.
I know saying sorry does not undo it. I am saying it anyway, because you should hear it from me before you hear anything else.
So the night does not do the damage that the argument started.
I am sorry for making you feel like you had to justify a feeling that was completely valid. That was the real mistake, and I see it now.
A long apology in a chat window gets read in three seconds between other notifications. The same words on a private page open slowly — one line at a time, with the photos from every group chat you have shared behind them and a folded letter they unfold themselves. Same words, completely different reception.

Reply to the original thing first, then apologise for the delay. Apologising first and never addressing what they actually said repeats the exact behaviour you are apologising for. Whatever you send, send it once and then stop. Repeated messages shift the weight of the situation from what you did onto how you are feeling about it, and your school friend then has to manage both.
Avoid anything that contains the word "but", anything that describes your intentions, and anything that ends in a question. Each of the three moves the conversation back to you — and for not replying, your school friend is not looking for your perspective yet.

Yes, and it is the option most people are switching to. A BuildNectic sorry website is a private apology page that opens slowly instead of in a notification bar — your words paced line by line, your photos, and a folded paper letter they unfold themselves. You personalise it in a few minutes, get a private link, and send it on WhatsApp — your school friend opens it in their browser with nothing to install and no account to create.
Shorter than you think. A long apology reads as a defence, because length invites explanation and explanation invites excuses. Two or three sentences that name what you did, without a single "but", outperform a paragraph almost every time — save the longer version for when you are face to face with your school friend.
No. The link opens full-screen in any browser on any phone or laptop — no download, no sign-up, nothing for your school friend to install. It works on Android and iPhone, and it stays online afterwards so they can reopen it later.
Silence after an apology is usually processing rather than rejection, and following it with a second message converts it into pressure. Send one message, make it complete, and then leave the next move to them. If several days pass, one short line that asks for nothing — not a repeat of the apology — is the most you should add.
