# Two-way SMS and conversational AI

SMS has one of the highest direct returns of any channel: 98% open rate, 45% reply rate, most messages read within three minutes. These modules turn one-way marketing texts into two-way conversations an AI can close.

## Key statistics

- 98% open rate and 45% reply rate for SMS; most read within 3 minutes
- Accent-free GSM-7 encoding fits 160 characters per SMS instead of 70, halving the monthly bill

## Recipes

- [Two-way sales and info SMS](https://aiemailcegeknek.hu/en/workflows/sms/conversational-sales-sms): When a customer replies to a text with a question ('Do you have a 42?', 'What's shipping?'), an AI agent answers in a human tone, with a natural 4–8 second delay, and closes: 'Yes, in black.
- [Missed-call text-back (SMS)](https://aiemailcegeknek.hu/en/workflows/sms/missed-call-text-back): 30 seconds after a busy or unanswered call a personal text goes out: 'Hi! I'm with a customer and couldn't pick up.
- [Interactive confirmation and no-show prevention](https://aiemailcegeknek.hu/en/workflows/sms/interactive-appointment-confirmation): 24 hours before: 'Hi Dóri! We expect you tomorrow at 14:30.
- [Dormant customer reactivation sprint](https://aiemailcegeknek.hu/en/workflows/sms/sms-reactivation-sprint): Contacts inactive for 6–18 months in the CRM or invoicing tool get a short, friendly, non-promotional text referencing their real history.
- [Google review funnel and reputation management](https://aiemailcegeknek.hu/en/workflows/sms/review-booster): 30 minutes after service: 'Thanks for choosing us! How satisfied were you, 1 to 5?' 4–5 goes straight to Google with a direct link; 1–3 opens a private complaint form and alerts the owner.
- [Webshop SMS rescue: abandoned cart, parcel locker, cash on delivery](https://aiemailcegeknek.hu/en/workflows/sms/webshop-sms-rescue): Cart abandoned → text 15 minutes later offering sizing help.
- [Quote follow-up by SMS](https://aiemailcegeknek.hu/en/workflows/sms/quote-follow-up-sms): 48 hours after a quote: 'Hi Péter, did our offer for the industrial flooring come through Tuesday? Any questions I can help with?' Three times the reply rate of another reminder email..
