Our commitment
Independent research methodology
Our researchers use a mix of verified reviews, independent research, and objective methodologies to bring you selection and ranking information you can trust. While we may earn a referral fee when you visit a provider through our links or speak to an advisor, this has no influence on our research or methodology.
Verified user reviews
GetApp maintains a proprietary database of millions of in-depth, verified user reviews across thousands of products in hundreds of software categories. Our data scientists apply advanced modeling techniques to identify key insights about products based on those reviews. We may also share aggregated ratings and select excerpts from those reviews throughout our site.
Our human moderators verify that reviewers are real people and that reviews are authentic. They use leading tech to analyze text quality and to detect plagiarism and generative AI.
How GetApp ensures transparency
GetApp lists all providers across its website—not just those that pay us—so that users can make informed purchase decisions. GetApp is free for users. Software providers pay us for sponsored profiles to receive web traffic and sales opportunities. Sponsored profiles include a link-out icon that takes users to the provider’s website.

Outbound as a Service overview
What is Outbound as a Service?
Outbound as a Service is a cloud-based, fully managed B2B email outreach platform that controls how cold emails are sent, tracked, and optimized across the full outbound sales cycle. The platform combines automated email infrastructure with human SDR execution, handling domain setup, inbox warming, prospect list building, copywriting, sending, and reply management on behalf of client teams.
Outbound as a Service targets B2B companies seeking to build or scale outbound pipeline without expanding internal headcount. It suits organizations across SaaS, professional services, staffing, and agency verticals that require consistent, high-volume outreach with deliverability controls. Configuration options cover campaign sequencing, audience segmentation, messaging personalization, and performance reporting, giving revenue and growth teams full visibility into outreach activity and conversion metrics.
Core business benefits include reduced time-to-pipeline, lower overhead compared to in-house SDR hiring, and predictable outreach volume managed by dedicated specialists. Deliverability infrastructure, including domain rotation and inbox health monitoring, is maintained by the service, reducing technical burden on internal teams.
