Some SMS platforms automatically block or filter messages with certain words due to carrier rules. Even if the message is legit, it still gets dropped.
What strategies are you using to bypaas these filters and keep delivery rate high?

I’ve seen better results when splitting campaigns into smaller batches and spreading them out over different times of day. Helps avoid traffic spikes that might trigger automated filters.

That's a smart move. Breaking down sends and avoiding peak triggers can really help maintain deliverability. I have noticed better sucess with that too, especially when rotating sender IDs.
 
I break up words with invisible characters — still readable, but avoids detection.

That's smart workaround. We have seen similar results using Unicode tricks or slight character swaps. Helps maintain delivery without hurting readability. Curious - have you tested it across different carriers? Some filters are stricter than others.

Yeah, I’ve tried it with a few carriers. Some catch it, some don’t. For me, AT&T worked fine, but T-Mobile flagged a few. I usually mix invisible characters with small spelling changes. It works better that way. Still testing what sticks best!

True. Mixing invisible characters with small spelling tweaks usually works better than using just one click. It kepps the message clear but still avoids some filters. Still testing it on different carriers to see what works best long-term.
 
We usually change letters, using similar letters or characters to replace letters in the words that may be blocked. For example, use α instead of a, capital i instead of l, number 1 instead of l, etc.
