CRM & B2B Email Deliverability: the technical infrastructure that makes your campaigns successful
HubSpot/Salesforce, DNS email, warm-up and standardisation of sales management.
CRM and email deliverability **involves configuring the technical infrastructure** that determines the real performance of your B2B prospecting. Without a solid foundation, emails end up as spam and leads get lost in the pipeline.
devlo configures the technical foundations: secondary sending domains, SPF/DKIM/DMARC authentication, progressive warm-up, box rotation, then CRM structuring (pipelines, properties, workflows, integrations).
With a sound technical base, your campaigns become more reliable, your sales force more visible and your management becomes measurable.

By Charles Perret, Founder, devloWhy does effective prospecting start with the CRM technical foundation?
Copywriting and targeting are not enough if emails don't reach the inbox. According to Gartner, companies with properly configured email authentication (SPF, DKIM, DMARC) achieve 15-20% higher inbox placement rates. That is why we treat deliverability as a priority before increasing volume.
In other words, CRM success comes down to data discipline. A clean pipeline, well thought-out properties and stable integrations directly improve the speed of commercial processing. The technical foundation determines whether your sales machine scales reliably or breaks under pressure.
In summary:
Key takeaways
- Proper SPF, DKIM, DMARC configuration improves inbox placement by 15-20%
- Always use secondary sending domains to isolate cold email risk from corporate communications
- CRM data discipline (clean pipelines, structured properties) accelerates sales processing
- Progressive warm-up over 4-8 weeks is essential before scaling email volume
