Who buys and manages Fastly inside a company?
Fastly is usually owned by Edge Cloud & Content Delivery. Decision-makers include CTO, VP of Engineering and VP of Infrastructure; Edge Platform Lead and Security Architect shape the choice, and DevOps Engineers and SREs use it day to day. Our Fastly list can include any of these roles.
Which Fastly products or editions can I target?
You can target accounts by the Fastly products they run, including Fastly CDN, Fastly Compute (Edge), Fastly Next-Gen WAF, Fastly DDoS Protection and Fastly Image Optimizer. Tell us which edition or module matters and we filter the list to those accounts.
What other software do Fastly customers use?
Fastly customers commonly also run AWS, Kubernetes, GitHub, Terraform and Datadog. Fastly is often connected to Google Cloud, so users of those tools overlap heavily. We can filter any list by this kind of stack overlap.
What are the main alternatives to Fastly?
The main alternatives to Fastly are Cloudflare, Akamai and AWS CloudFront. We also keep verified user lists for Cloudflare and Akamai, which is useful for competitive displacement campaigns.
When are Fastly customers most likely to buy?
Buying triggers we track for Fastly accounts include CDN renewal, major live event, WAF replacement and edge compute project. A common pain point is edge performance at peak: traffic spikes stress origins.
Can Data InfoMetrix deliver a free sample Fastly contact list before ordering?
Yes. Data InfoMetrix delivers a complimentary 10-record sample tailored to your target Fastly criteria—including target job titles, company size, and region—delivered within one business day with no obligation.
How does Data InfoMetrix guarantee email deliverability for Fastly contacts?
Data InfoMetrix provides a 99% email deliverability guarantee on all Fastly datasets. Every contact record undergoes real-time email verification within a 30 to 45-day refresh cycle, backed by a 1:1 hard bounce replacement policy for 30 days after delivery.
Sourcing and compliance. Business contacts come from public company sources, professional directories and opt-in publishing partners, then go through SMTP verification and human review. Lists are for B2B outreach: include an unsubscribe link and honour opt-outs (CAN-SPAM), and have a lawful basis such as legitimate interest when you email people in the EU or UK (GDPR).
