A visitor on mobile gets pulled away mid-conversation. Their kid wants attention, the bus arrives, a meeting starts. They had three messages from the bot with the answer to their question, and now they're gone. Five minutes later they're somewhere else, can't remember the answer, and won't reopen the laptop to check. The reasonable thing to do is text them the relevant part of the conversation so it lives in their pocket.

SleekAI does this with an SMS fallback path. The bot reads wp_posts, WooCommerce orders, custom postmeta, and whatever else you map. When the visitor asks for a text follow-up, when they appear about to leave (page unload, idle timeout), or when the bot itself can't fully resolve and wants a callback path, it fires a webhook to Twilio or another HTTPS SMS provider. The message contains the relevant answer, a link back to the site, and a reply-to number if you want two-way SMS.

The other side of this pattern is on-call alerting. A high-priority chat (urgent support, abandoned cart over a threshold, qualified lead with budget) can fire an SMS to a human on-call so they reach back out. Both patterns share the same webhook plumbing. SleekAI hands the formatted message to Twilio or your SMS gateway of choice, and you don't pay for a separate chatbot vendor's SMS add-on tier.

Most chatbot conversations end one of two ways. The visitor gets the answer and leaves happy. Or the visitor gets distracted, closes the tab, and is never seen again.

Email recap helps for the second case, but it's slow, often ignored, and gets caught in spam. SMS lands on the phone in seconds and is read. For mobile-heavy industries and time-sensitive purchases, that difference shows up in conversion data.

SleekAI builds SMS fallback as a webhook rather than a vendor lock-in feature. You pick Twilio, Vonage, MessageBird, or whoever has the best rate in your region, and the bot fires the payload at their API. You pay only the per-message cost from your provider, not a per-message uplift to a chatbot vendor.

For most US-based businesses that means under a cent per message at scale. Compliance is the trickier piece. TCPA and CTIA rules in the US require explicit consent, opt-out language in every message, and consent records that can be produced on demand.

SleekAI handles all three. The bot asks for consent explicitly before sending the first SMS, records the consent and number in the database, and includes STOP and HELP language in every outbound message. Replies of STOP mark the number as opted out automatically and the bot refuses to send to opted-out numbers thereafter.

Two-way SMS turns the recap pattern into something closer to a sustained conversation. Visitors who can't or won't return to the site can keep replying by text, and the team replies from the WordPress chat panel. The transcript stays in one place, the visitor stays in the channel they prefer, and the team doesn't context-switch.
