Can one campaign call customers in different languages?
Not in the sense of one agent picking a language per contact. Outpero's agents run in one live language at a time and follow a caller into English. For a mixed list, split the CSV by language and run one campaign per language. This keeps scripts natural and makes each language's results easy to compare.
How language works in a campaign
A bulk campaign is an AI conversation with every contact on an uploaded CSV, with scheduling, calling windows, retries, callbacks and DND screening. The agent that makes those calls speaks one live language, and in that language it switches to English when the caller does. It is not a menu where a caller pushes a button for a language.
How to run a mixed-language list
- 01Add a language column to your CSV, using the language the customer uses with you.
- 02Filter the file into separate CSVs for Hindi, Telugu, Tamil, Marathi, Kannada, Malayalam and English.
- 03Create one agent per language with the script written natively, not translated mechanically.
- 04Start each campaign with the same offer, so results across languages stay comparable.
- 05Review transcripts after the first day and fix any line callers ask to repeat.
Why splitting beats one multilingual script
- —Each script can use the right honorifics, numbers and local examples.
- —Calling windows can differ by region without changing the others.
- —Dashboard analytics show which language converts better, so budget follows results.
- —A problem in one language does not stall the others.
Channels decide how many run at once
Concurrency is sold as channels: each channel is one call at a time on your number, at ₹649/month, and the dedicated number includes the first. Running three languages in parallel means three channels. If channels are limited, run the languages one after another. Roughly, each channel works through about 55 dials an hour.
When the caller replies in another live language
If a Hindi campaign reaches someone who answers only in Telugu, do not expect a smooth recovery. The transcript will show the mismatch, so move that contact to a Telugu list. Where transfer to your team is configured, the call can also be handed to a person who speaks the language.
Because the price per minute is the same in every language, splitting lists adds no cost beyond channels.

Follow-up questions
Does each language need its own phone number?
+
No. Languages are about the agent and script, not the number. One dedicated number can be used for campaigns in different languages, and channels decide how many calls run at once. If you want separate caller identities per region, add numbers at ₹649/month each.
