US & Canada Messaging Reach Playbook: Efficiently Reach American and Canadian Customers with iMessage & RCS Number Screening

The North American market is the core battleground for teams expanding from China to the US and Canada. However, the high bounce rate of traditional SMS mass sending and the limited penetration of WhatsApp in the region leave many teams struggling with low reach efficiency and wasted costs. Apple devices account for about 60% of the US smartphone market, making iMessage the default messaging channel. Meanwhile, as carriers gradually deploy RCS (Rich Communication Services), the interactivity of messages on Android users is also rapidly improving. How to precisely find numbers that support iMessage or RCS and are in an active state has become the key to message reach in the US and Canada for overseas marketing.

This article combines KK-DATA’s global number generation, iMessage/RCS number screening, and data deduplication capabilities to provide you with a complete North American playbook, from number construction to high-value list export.

Why Does the US & Canada Market Need Dual-Channel Reach via iMessage and RCS?

In the United States and Canada, iOS and Android devices each account for nearly half of the market, but messaging app habits differ significantly from Asian markets:

iMessage: Natively integrated into iOS, requiring no additional app installation. It boasts high open rates, with read rates exceeding 90%. Compared to WhatsApp, US and Canadian users rely more on iMessage for daily communication. Reaching users via iMessage bypasses the limitations of “WhatsApp not installed” or “privacy settings rejecting messages from non-contacts.”
RCS: As an evolution of SMS, RCS supports images, videos, and interactive buttons. Carriers (e.g., T-Mobile, Verizon, AT&T) have widely adopted it in North America. RCS messages appear directly in the default Android messaging app without requiring a third-party app, making it suitable for rich media marketing.
Traditional SMS Limitations: Plain text, 200-character limit, easily flagged as spam, and high bounce rate (approx. 15%–30% due to invalid or deactivated numbers). WhatsApp usage in North America is far lower than in Latin America and Europe; a large number of target users are inactive.

Therefore, for overseas teams, simultaneously covering both iMessage and RCS channels can maximize user reach in North America. The prerequisite is first screening for active numbers that support the corresponding channel, avoiding blind mass sending.

Building a US & Canada Number Database: Global Number Generation and Screening

Whether you already have a customer list or are starting from scratch, a high-quality number database is the first step. KK-DATA offers two ways to build a US/Canada number pool.

Randomly Generate Numbers by Country/Number Block

In the console, select the “Global Number Generation” module:

Select country: United States or Canada (supports 240+ countries).
Select number block: Can be narrowed down to state, city, or carrier number blocks (e.g., 310-XXX US mobile number block).
Set quantity: Up to approximately 1 million per generation, completely free.

The generated numbers are random numbers conforming to real North American area code structures, suitable as a cold-start probe pool. However, note that generation does not guarantee every number is in use; subsequent screening verification is required.

Import Your Own Customer List and Deduplicate

If you have an existing historical list or purchased external data, upload a CSV or TXT file in the console under “Number Import.” The system will automatically compare against the data deduplication repository, removing numbers that have been previously tested to avoid duplicate charges.

The deduplication repository is user-account-based and shared across tasks. It is recommended to import historical results into the repository before each new import, then upload the new list.

Practical iMessage & RCS Number Screening: From Number Pool to Effective Reach

After obtaining a number pool, the core action is to batch test whether each number supports iMessage or RCS, combined with activity filtering. KK-DATA packages these tests as independent tasks, charging per number.

Batch Test iMessage & RCS Activation Status

Create an “iMessage Screening” or “RCS Screening” task in the console:

Select number source: the number list you just generated or the imported CSV.
Configure test type: iMessage activation (check if the number is associated with an Apple ID and iMessage is available); RCS support (check if the number supports the RCS protocol, requires carrier cooperation).
Before submission, the system shows an estimated charge; submission is blocked if the balance is insufficient.
After the task completes, results are automatically exported (CSV/TXT), including “activated/not activated” status. You can export using tgid or wsid (iMessage does not support tgid, but you can directly export the number list).

<Callout type="info" title="Task Cost Estimate Tip">
Before submitting, you can view the estimated charge in the console. Charged per record with no subscription, keeping trial costs low. Specific unit prices are shown in the console's real-time pricing.
</Callout>

Optimize Resources by Combining Activity and Effective Numbers

Simply testing iMessage activation is insufficient — if a number has been unused for a long time, sending will still yield no response. It is recommended to further filter based on “effective number” or “activity (last 30 days)” after confirming iMessage availability:

First round: iMessage screening → export the activated list (assume 20%–40% of the original pool).
Second round: Use the activated list as the new task source, select “Activity Detection (30 days)” → filter numbers that have had network activity in the last 30 days (about 50%–70% of the activated pool).

The final list contains numbers that are iMessage-available and active, significantly improving open rates after reaching. Similarly, RCS testing can be performed independently. Since the two channels belong to different test types, tasks must be submitted separately.

Case Scenario: A US/Canada Reach Transformation for an Overseas Marketing Team

The following is a virtual scenario with no real customer data.

An independent e-commerce site promotion team targeting US cross-border consumers previously used SMS mass sending for promotional notifications, sending 500,000 messages per month. The bounce rate was as high as 22%, with only about 390,000 actually delivered, and the final click-through rate was only 0.8%. They decided to switch to an iMessage+RCS dual-channel reach strategy.

Implementation Steps:

Number Generation: In KK-DATA, selected US number blocks for California, New York, and Texas, randomly generating 200,000 numbers.
iMessage Screening: Submitted an iMessage activation test. With sufficient balance, after task completion, 48,000 activated numbers were obtained (24% of the total).
Activity Filtering: Ran a “last 30 days activity” test on these 48,000 numbers, yielding 31,000 high-potential numbers (activity rate 64.6%).
RCS Supplement: Submitted a separate RCS test on the original 200,000 numbers, obtaining 35,000 numbers supporting RCS (17.5%). Then filtered for activity to get 21,000.
Deduplication & Merge: Used the data deduplication repository to merge both lists, deduplicating to obtain approximately 50,000 unique valid numbers.

Result Comparison: Based on these 50,000 numbers, targeted iMessage and RCS sending (executed by a third-party platform) reduced the bounce rate to below 3% and increased the click-through rate to 3.5%. Overall reach cost decreased by approximately 40%, with significant ROI improvement.

Data Deduplication and Cost Control: Avoid Wasting Repeated Checks

When multiple screening tasks share the same number source, the most overlooked issue is duplicate charges. For example, after first testing iMessage activation, then testing the same batch for RCS — if numbers overlap, the system charges for both tasks, meaning the same number is tested twice, wasting balance.

KK-DATA includes a built-in data deduplication repository that supports importing all historical test results (automatically marking tested numbers and test types). Before submitting a new task, select “Exclude already tested numbers from the repository” to skip duplicates.

<Callout type="warning" title="Avoid Duplicate Charges">
When multiple screening tasks use the same number source, first import historical results into the deduplication repository. The system will automatically skip already tested numbers, ensuring every cent is spent on new numbers.
</Callout>

Best Practice: Before each week or batch of tasks, force import all previous exported results into the deduplication repository, then upload the new list. This is especially important when multiple team members operate under the same account — the deduplication repository is the core tool for cost control.

Implementation Tips and Best Practices

Summary of the execution checklist for US/Canada iMessage/RCS reach:

Single task limit: Approximately 1 million records. For large lists exceeding 1 million, split them into multiple subtasks to avoid exceeding the limit.
Testing sequence: First use iMessage screening to filter effective numbers (since iMessage active users tend to be of higher quality), then conduct RCS testing on that result (if dual-channel is needed), avoiding full RCS testing from the start.
Monitor real-time unit prices: Different test types and countries have different unit prices. Always check the estimated cost in the console before submitting.
USDT recharge: Minimum approx. 50 USDT; balance updates automatically after recharge. No subscription plans; balance is valid indefinitely.
Enable Telegram notifications: Bind your Telegram account (@kkdata_robot) in the console to receive automatic push notifications after task completion, eliminating the need to repeatedly refresh the page.
Compliance note: KK-DATA only provides number status detection and does not send messages. When conducting actual marketing, please comply with Apple and carrier regulations regarding iMessage/RCS commercial messages to avoid complaints.

Frequently Asked Questions

Q: Can iMessage and RCS testing be completed in a single task?
A: Currently, iMessage and RCS are separate test types and require separate task submissions. It is recommended to first screen for iMessage-effective numbers, then perform RCS testing on that result to control costs.

Q: Do the generated US/Canada numbers include virtual or invalid number blocks?
A: KK-DATA generates numbers based on real number blocks but does not guarantee that every number is actually assigned by a carrier. It is recommended to first run “iMessage activation” or “effective number” screening after generation to obtain reachable numbers.

Q: Can new tasks be submitted with insufficient balance?
A: No. The system checks whether the balance is sufficient to cover the estimated cost before submission. If insufficient, you must first recharge with USDT (minimum approx. 50 USDT).

Q: Can the deduplication repository be used across workspaces?
A: Currently, the deduplication repository is based on a single user account, shared among all tasks under the same account. It does not work between different accounts. It is recommended that the team use the same account to manage all screening tasks.

Q: Is it compliant to use iMessage or RCS for marketing messages in the North American market?
A: Compliance depends on local laws and platform policies. KK-DATA only provides number status detection and does not send messages. We recommend that you follow Apple and carrier regulations regarding iMessage/RCS commercial messages to avoid complaints.
