Campaign Setup Steps
Best Practices
Optimal Calling Hours
In India, 9 AM – 7 PM IST yields the best answer rates. Avoid calling before 9 AM or after 7 PM. For rural segments, mid-morning (10 AM – 12 PM) and late afternoon (3 PM – 6 PM) tend to perform best. Never schedule calls on national holidays.
Retry Strategy
3 attempts with 4-hour gaps is the benchmark for most use cases. Dialing more than 3 times in a day increases complaint rates without meaningfully improving contact rates. Space retries across different times of day to catch different availability windows.
Language Matching
Use geography or CRM language preference data to assign the right language per contact. A campaign targeting Maharashtra can use Marathi as primary with Hindi fallback. Matching language to preference increases engagement rates significantly.
Script Opening Tips
Keep your opening under 10 seconds and state the purpose in the first sentence. Introduce a callback option early (within the first 30 seconds) so resistant customers have a graceful exit — this reduces hang-ups and preserves a positive brand impression.
