"Rock-Solid Cold Email Infrastructure That Protects Our Primary Domain"

5/5

What do you like best about Prospectout?

What stands out most for us is that ProspectOut treats cold email as an infrastructure and deliverability problem, not just a copywriting exercise. As a growing IT services company with a team of under 50 people, protecting the reputation of our primary domain while building a dedicated outbound channel was important because email is a core part of our sales strategy.

The combination of secondary domains, professional inbox setup, SPF/DKIM/DMARC authentication, warm-up, deliverability monitoring, and campaign management gave us a solid foundation for running outbound email without putting our main business email at risk.

What do you dislike about Prospectout?

The main consideration is the time required for proper email infrastructure preparation before campaigns can run at full capacity. Domain setup and warm-up are necessary for good deliverability, but it means you shouldn’t expect to start sending large volumes right away.

It would also be useful to have more detailed deliverability reporting available from day one so we could monitor inbox placement and campaign performance more closely early on. Review collected by and hosted on G2.com.

Recommendations to others considering Prospectout:

I would recommend ProspectOut to other smaller B2B technology and IT services companies (especially in the 11–50 employee range) that want to establish a professional cold-email infrastructure without having to build the technical setup themselves.

The strongest value is the combination of infrastructure configuration, deliverability preparation, campaign execution, and ongoing optimization rather than simply sending emails on a client’s behalf. Review collected by and hosted on G2.com.

What problems is Prospectout solving and how is that benefiting you?

The main problem we faced was building a reliable outbound email channel without putting our existing company domain and reputation at risk.

ProspectOut handled the technical side for us secondary-domain setup, mailbox creation, DNS authentication, inbox warm-up, and ongoing deliverability management. Once the infrastructure was ready, we combined it with targeted prospect lists, personalized sequences, A/B testing, and campaign optimization.

For a smaller IT services company like ours, this eliminated most of the technical work involved in building an outbound email system internally and gave us a dedicated infrastructure for prospecting. Review collected by and hosted on G2.com.
