When to use which link
Call vs. SMS. Always match the channel to how the conversation actually happened. If the purchase happened during a call, any SMS follow-up referencing the same offer needs its own link with the SMS channel selected — don't reuse the call link.
Outbound vs. Cross-sell. Outbound is when you're calling an assigned lead or an old lead to sell the original product they inquired about. Cross-sell is when you're reaching out as part of a cross-sell list, or when a lead has already purchased their main product and you're now offering an upsell.
Always shorten your links. Shortened links improve deliverability, especially over SMS. Don't send the long version with raw UTM parameters — always click "Shorten link" first.
To enable link shortening: open this page's code and paste your Cloudflare Worker URL into the API_ENDPOINT variable near the bottom of the script block.
