A win-back sequence has two jobs: give quiet contacts one clear reason to come back, and let you retire the ones who do not.
Re-engagement email automation that also cleans your list runs entirely on official APIs — the Meta Graph API for Instagram, the WhatsApp Business Platform for WhatsApp and the Telegram Bot API. Repli never automates a personal account, never scrapes and never uses an unofficial client, so your number and your account stay safe. Rate limits, messaging windows and template rules are enforced by Repli before a message is ever sent.
You can use re-engagement email automation that also cleans your list on the free plan: 15 credits to start, 5 new credits every day and a daily cap of 20. Pro is ₹499/month, Pro+ is ₹999/month for the AI features, and Pro Business starts at ₹2,999/month for teams that need the WhatsApp support agent builder and multiple seats.
When the contact never consented, when the address already bounced or complained, or when they will no longer recognise you.
Removing addresses that never engage reduces complaint and bounce pressure, but no platform can promise a deliverability or inbox-placement outcome.
