Truth: Posting private chat screenshots isn’t always legal.

Screenshot? Fine.
Sharing publicly? Risky.
If it exposes private info harms reputation, or violates consent you could face legal action.

If it happens Save proof. Report. Talk to a lawyer.

@subham_agrawal_ Well said. App passwords feel simple, but OAuth2 is what actually scales cleanly.

[Manu @isendmanu]

Gmail app passwords are a shortcut.
And shortcuts break systems.
OAuth2 > app passwords

We added it in iSend:
• No credentials stored
• Connect via Google
• Access control stays clean

App passwords = edge cases
OAuth2 = default

[Manu @isendmanu]

Stop using Gmail app passwords.

They’re fragile, hard to manage, and easy to misuse.

We just added OAuth2 (Connect with Google) in iSend:

• No stored passwords
• 1-click connect
• Revoke anytime
Cleaner setup.
Reply GMAIL for checklist.

Growth is colourful.

But only if it actually delivers.

This Holi, don’t just scale traffic - fix the pipeline carrying it.

Reliable emails. Real expansion.

Happy Holi 🌈

Most teams only realize this when OTP complaints start.

Your WhatsApp messages aren’t failing.

They’re being throttled. 🧵👇

Have you ever seen WhatsApp delivery slow down “mysteriously”?

[Manu @isendmanu]

Turns out, the welcome email isn’t a nice-to-have.

It’s the bridge between signup and first action.

Without it, users don’t fail loudly.
They quietly leave.

What’s the first email a new user gets from your product?

[Manu @isendmanu]

Nothing was broken.

But activation dropped 42%. 🧵👇

[Manu @isendmanu]

We skipped the welcome email.

Thought users would “figure it out”.

Silent failures are the most expensive ones.

[Manu @isendmanu]

This WhatsApp template didn’t fail.

It got silently rejected 🧵👇

[Manu @isendmanu]

WhatsApp systems don’t judge text.

They judge intent.

And too much flexibility looks risky.
That’s why these failures don’t throw errors.

Messages just stop reaching users.
Most teams discover this only after production.

How many variables do you allow per template?
