Best practices and compliance
Data quality and updates
You must guarantee the quality and freshness of your data to succeed in your B2B prospecting. A well-maintained contact database allows you to avoid errors and increase the relevance of your campaigns. Implement clear and standardized rules to control quality. Use thresholds, alerts, and scoring to quickly detect anomalies. Continuously monitor quality using dashboards. Structure your repositories to ensure data remains consistent and shared across teams. Clarify everyone's roles to avoid ambiguities in data management.
Define quality rules and apply them consistently.
Monitor quality with dashboards and alerts.
Structure your repositories to guarantee data uniqueness.
Assign specific responsibilities to each team member.
An outdated database can lead to transcription errors , duplicates, a high bounce rate, and irrelevant messages. Therefore, you should regularly update your contacts and delete unnecessary information.
Tip: Continuous monitoring allows you to quickly identify anomalies and act before they impact your results.
Compliance with the GDPR
Compliance with the GDPR is essential when building a B2B contact list. You must ensure complete transparency regarding the origin and use of the data. Inform the individuals concerned during the initial communication, as required by Article 14. Respect the right to object and always offer an unsubscribe option. Opt-out remains acceptable in B2B, but you must verify its business relevance and conduct a cost-benefit analysis.
To ensure compliance, adopt the following best practices:
Limits data collection to what is strictly necessary.
Specify the legal basis and consent in your forms.
Map the data flows to ensure their traceability.
Encrypts the data and restricts access to authorized individuals.
Archives or deletes data after 12 months of inactivity.
Set up logs to manage incidents and notify quickly in case of problems.
Continuously monitor and improve your workflows to remain compliant with regulatory changes.
GDPR Practices | Objective |
|---|---|
Minimal collection | |
Flow mapping | Traceability and security |
Access controls & encryption | Data protection |
Conservation policy | Compliance with legal deadlines |
Deliverability optimization
You want your emails to reach your prospects' inboxes. Use a professional platform to send your messages and adhere to B2B best practices. Prioritize quality over quantity: a relevant email each month is far better than frequent, untargeted mailings. Ensure your email lists are compatible with tools like Mailchimp or Brevo.
Maintain a clean database by removing inactive addresses and validating emails before each send. Integrate automated routines to handle bounces and reactivate inactive contacts.
Use professional tools for sending.
Validate addresses before each campaign.
Delete inactive contacts regularly.
Implement reactivation campaigns.
Tip: A clean database and targeted emails increase deliverability and reduce the risk of your messages ending up in spam.
Use case for cascade enrichment
Practical example
Imagine you work for a company that targets decision-makers in the service sector. You have a database of 5,000 contacts, but you notice that much of the information is missing or outdated. You then decide to implement a cascading list enrichment strategy to improve the quality of your database.
You start with a quick audit. You identify the priority fields: email, phone number, industry, job title, and social media presence. You use a platform like Magileads to connect your database to over 40 data providers. The tool enriches each contact in several steps. It first verifies emails and phone numbers, then adds firmographic and digital information.
You notice that some contacts are receiving RCS (Trade and Companies Register) data that was previously missing. You also add information about company size and revenue. You then use a clustering algorithm to segment your database by job title and industry. You create homogeneous groups to personalize your campaigns.
Before the data enrichment process, you struggled to reach the right people. Afterward, you have a structured database with valid email addresses, up-to-date phone numbers, and LinkedIn profiles for more than half of your contacts. You can then launch a targeted prospecting campaign for new RCS subscribers.
Results and lessons learned
After the enrichment, you quickly measure the impact on your campaigns. You notice several positive changes:
The conversion rate varies from 2% to 15% depending on the segments created by clustering.
On a targeted campaign of 1,200 new RCS subscribers, you achieved a conversion rate of 7.8% , whereas the same campaign on an unqualified list was capped at 3.2%.
Your email open rate increases by 40% and your appointment booking rate increases by 25% thanks to the integration of RCS data.
You reduce your cost per lead by 30% and your cost per thousand impressions decreases by 20% compared to your previous campaigns.
Indicator | Before enrichment | After enrichment |
|---|---|---|
Average conversion rate | 3,2 % | 7,8 % |
The opening rate | +0 % | +40 % |
Making appointments | – | +25 % |
Cost per lead | 100 € | 70 € |
Cost per thousand impressions | 10 € | 8 € |
