Methodology and sourcing behind the figures shown above.
Email deliverability monitoring and sender reputation
Estimates use published market reports in the provided search results. Both Business Research Insights and Fortune Business Insights report the email deliverability market around USD 1.35B (2025–2026); reported CAGRs range ~8.47%–9.25%, averaged to ~8.9% for growth potential.
- The global email deliverability market size is projected at USD 1.35 Billion in 2026... registering a CAGR of 8.47% during the forecast from 2026 to 2035.
- The global email deliverability tools market size was USD 1.35 billion in 2025... projected to expand from USD 1.48 billion in 2026 to USD 3.00 billion by 2034, growing at a CAGR of 9.25%.
Email program operations and fractional teams
Primary anchor: Fortune Business Insights reports the global email marketing software market at USD 1.7B (2025) with ~10.6% CAGR (2026–2034). The target segment (fractional email program operations: deliverability staffing, monitoring, audits, remediation, implementation) is a services/consulting subset of the broader email ecosystem and is therefore materially smaller than the software market. Using the software market as a baseline and accounting for rising adoption of fractional/resourced models (noted 57% increase in fractional team usage 2020–2022), I estimate the fractional email program operations market at roughly $0.5B today with higher-than-software growth potential; I assign a 14% CAGR reflecting continued email investment plus faster uptake of fractional staffing and deliverability services.
Sender reputation and ISP remediation
None of the provided search results include explicit market-size or CAGR figures. I estimated using market hierarchy reasoning: the global email marketing/ESP ecosystem supports a deliverability/remediation submarket (providers shown in results: deliverability blogs and services). Assuming deliverability services represent a small share of the broader email market and that sender-reputation & ISP-remediation is a niche within deliverability, I used conservative share assumptions (deliverability = ~5–10% of email marketing; sender-reputation remediation = ~5–20% of deliverability) and selected a midpoint estimate of ~$150M. Growth (CAGR ~15%) reflects higher-than-average expansion driven by rising complexity of ISP requirements, increased use of programmatic email at scale, and demand for specialist remediation services.
Email authentication and brand protection
Search results show the global authentication & brand protection market at roughly $2.7–3.3B (2023–2025) with CAGR estimates 8–13%. Email authentication (SPF/DKIM/DMARC/BIMI/VMC) is a niche subset of digital/brand-protection services. Using the reported market as a baseline (~$3.0B) and estimating email-authentication's share at about 5–7% (SaaS/email-specific solutions, growing adoption of DMARC/BIMI, and services for inbox brand protection), the segment is estimated near $0.2B. Email-authentication adoption and SaaS delivery suggest faster growth than the overall market; a CAGR of ~15% reflects elevated demand from anti-phishing, deliverability, and brand-display initiatives versus the broader market CAGR.
