Mobile Number Verification | Conversive

Improve campaign quality by sending messages only to numbers identified as valid mobile destinations.

Why it matters

Campaign lists can contain invalid numbers or fixed-line numbers that cannot receive mobile messages. Mobile Number Verification checks campaign destinations before sending, helping reduce avoidable delivery failures and unnecessary messaging spend.

What the feature does

Verifies destination numbers used in supported campaigns before they are sent to the messaging provider.
Allows valid mobile numbers to continue through the normal campaign send process.
Skips numbers identified as invalid or fixed-line and records an appropriate reason in message history.
Reuses previously verified results when available, avoiding unnecessary repeat verification lookups.

How it works

1. Check existing verification data

The system first checks whether the destination number has already been verified. If a usable result is available, that result is reused.

2. Verify new numbers

If there is no existing verification result, the number is checked using an external number-verification service.

3. Decide whether to send

Numbers identified as valid mobile destinations continue to the messaging provider. Invalid or fixed-line numbers are skipped.

4. Reuse the result

The verification result is stored so future supported campaign sends can reuse it instead of repeating the external lookup.

What customers can expect

Area	Expected behavior
Campaign delivery	Only numbers identified as valid mobile destinations are passed for sending.
Invalid / fixed-line numbers	The message is not sent to the provider, and the message history records the applicable verification outcome.
Repeat checks	Previously verified results are reused where available, reducing duplicate external verification calls.
Verification usage	Where verification usage is billable, charges apply to new external verification lookups. Reused internal verification results do not create a new external lookup charge.
One-to-one messaging	Number verification is not applied to one-to-one messages or replies under the current scope.

Supported scope

Experience	Support	Notes
Salesforce campaigns	Supported	Verification is performed before the message is sent to the provider.
Zoho campaigns	Supported	Applies to supported campaign messages.
Conversive campaigns	Supported	Applies to supported campaign messages.
One-to-one / replies	Not in current scope	Messages continue through the standard one-to-one send flow.

Key benefits

Reduce avoidable messaging cost: Prevent campaign sends to destinations already identified as invalid or fixed-line.
Improve campaign quality: Increase the proportion of campaign traffic sent to usable mobile destinations.
Avoid repeated verification cost: Reuse existing verification results where available.
Improve data quality: Maintain verification outcomes that can be reused across future supported campaigns.

Important notes

Number verification identifies whether a destination is suitable for supported mobile messaging; it does not guarantee message delivery. Delivery can still depend on carrier, provider, consent, content, account configuration, and other messaging conditions.
Country and number interpretation use the account configuration and available number context.
Feature availability, pricing, and billing treatment may depend on the customer plan, account configuration, and commercial agreement.
The feature may need to be enabled for the customer account before it is applied to campaigns.


Summary	Mobile Number Verification adds a quality check before supported campaign sends, helping customers avoid sending to known invalid or non-mobile destinations while reusing prior verification results whenever possible.
