Methodology and sourcing behind the figures shown above.

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.

Email deliverability and sender reputation management

Primary sources in the search results report a consistent market baseline (~USD 1.35B) for email deliverability tools/deliverability market. BusinessResearchInsights projects USD 1.35B in 2026 and a long‑term CAGR of 8.47% to 2035; The Business Research Company reports a similar 2025 baseline ($1.35B) with shorter‑term forecasts (CAGR ~10.6% to 2030). I use the USD 1.35B baseline and the 8.47% CAGR (BRI) as the conservative long‑term growth estimate for this segment.

Email verification and list hygiene

Primary estimate anchored to industry report for the bulk email verification segment (WiseGuy) which values the 2025 market at about USD 1.13B and projects an 8.3% CAGR (2026–2035). Other available reports show a range (MRI/linked source: USD 1.65B in 2025, 10% CAGR; BusinessResearchInsights: USD 0.15B in 2026, 8.6% CAGR) reflecting differing definitions and scopes. I selected the WiseGuy bulk-market figure as the conservative, market-relevant anchor and used its CAGR for growth potential.

Content quality and spam filter optimization

Estimation uses available market reports for related segments as bounds. MRFR’s Web Filtering market (USD 2.9B in 2024, CAGR ~12.1%) and Zion’s broader Enterprise Spam Filter figure (USD 138.65B in 2023, CAGR 15%) define high/low context. Content-quality and inbox-placement optimization is a niche subset of web/email filtering and deliverability services; I conservatively estimate it at roughly ~10% of the focused web-filtering/content-filtering market (≈USD 2.9B), yielding ~USD 0.3B in 2024, with growth potential aligned to web-filtering CAGR (~12%).

Email deliverability and reputation management

Estimate uses the Business Research Insights report for the dedicated 'email deliverability' segment (explicit 2026 size and 2026–2035 CAGR). I included MarketResearchFuture's broader Email Market sizing as context showing a larger adjacent market and stronger overall email-sector growth, which supports the stated deliverability CAGR as a plausible segment-level trajectory given regulatory and e‑commerce drivers cited in the results.
