[Talk to a deliverability expert](https://meetings-eu1.hubspot.com/lawrence-heslin/site?utm_source=google&utm_medium=search&utm_campaign=casestudy) Inbox Placement Rate 25%95% Unique Open Rate 14%18% In BriefBlaze is an all-in-one, AI-powered marketing and sales platform for small and medium businesses. IndustryMartech: AI marketing & sales platform for SMBs - B2B SaaS. ChallengeSpam placement at all major destinations, with inbox placement under 25% and a unique open rate of just 14–18% — a near-total loss of email as a reliable channel, transactional mail included. SolutionMailSoar helped Blaze separate transactional and marketing email to rebuild sender reputation and reach 95% inbox placement. Outcome- Primary inbox placement at all major B2B destinations. - Separating transactional from marketing traffic means Blaze's critical account and product emails are no longer hostage to marketing sending patterns. - Inbox placement jumped from under 25% to 95%, giving Blaze a sustainable, segmented email program it can keep scaling without repeating the same reputation collapse. Duration6 months. 2M emails / month Inbox Placement Rate 25%95% Unique Open Rate 14%18% IP / Domain reputation BadHigh The ClientThe ChallengeThe Diagnosis As an AI marketing platform, Blaze relies on email for transactional, automated, and marketing communication alike — so when all three shared the same domains and IP infrastructure, a reputation hit on one type dragged down the others, including the transactional emails critical to the product experience. At the time, Blaze was sending over 2M emails/month through Iterable. Blaze's case is a shared-infrastructure reputation collapse: • No separation between email types: transactional, automated, and marketing emails all ran through the same domains and IP infrastructure, so reputation damage from one type spilled directly into the others. • Critical mail exposed to marketing risk: transactional emails — the ones customers most need to receive — carried the same reputation baggage as bulk marketing sends, with no protective boundary. • No dedicated warmup or migration path: without segmented infrastructure, there was no way to rebuild reputation for one email type without being dragged down again by the others. The concrete result: spam placement at all major destinations, with inbox placement under 25% and a unique open rate of just 14–18% — a near-total loss of email as a reliable channel, transactional mail included. MailSoar moved Blaze to a higher-quality Iterable IP pool and set up custom return-path, tracking, and image domains, separating transactional and marketing traffic by subdomain and IP. The active database was cleaned before migration, marketing email was rewarmed starting from roughly 500 engaged users a day, and volume was scaled up gradually based on engagement and reputation — prioritizing recent openers and applying sunset rules along the way. Automated campaigns were migrated one at a time, sign-up consent and expectations were tightened, and DMARC was strengthened once every legitimate sending source was properly authenticated, all under continuous monitoring of reputation, inbox placement, bounces, and complaints. ## What we did ## How MailSoar helped Blaze rebuild Sender Reputation on Iterable A 5-Step Infrastructure Overhaul 1. 1**Infrastructure separation** Migration to a higher-quality Iterable IP pool, with custom return-path, tracking, and image domains, and transactional traffic split from marketing traffic by subdomain and IP. 2. 2**Database cleanup and rewarming** The active database was cleaned before migration, and marketing email was rewarmed starting from roughly 500 engaged users a day on the new infrastructure. 3. 3**Gradual scale-up with engagement priority** Volume was increased step by step based on engagement and reputation signals, prioritizing recent openers and applying sunset rules to unengaged contacts. 4. 4**Phased automation migration and consent improvements** Automated campaigns were migrated one at a time to avoid disrupting reputation gains, alongside tighter marketing consent and clearer email expectations at sign-up. 5. 5**Monitoring and authentication hardening** Ongoing monitoring of reputation, inbox placement, bounces, and complaints, with DMARC strengthened once every legitimate sending source was fully authenticated.

Because mailbox providers judge reputation at the domain and IP level, not per email type — so if marketing sends generate complaints or low engagement, transactional emails on the same infrastructure suffer too, even though customers actively want to receive them. Separating the two was the turning point for Blaze, taking inbox placement from under 25% to 95% in 6 months. ## MailSoar at a glance MailSoar is an international email deliverability consultancy specializing in inbox placement, sender reputation, email authentication and email infrastructure. 25 Experts Senior deliverability consultants 500+ Clients In 20+ countries 4.9/5 Trustfolio 200+ verified customer reviews **Services**[Find](/services-solutions/deliverability-audit/) (audit) · [Fix](/services-solutions/infrastructure-setup/) (recovery) · [Grow](/services-solutions/recommendation-implementation/) (scaling) · [Run](/services-solutions/ongoing-support/) (monitoring) **Expertise**SPF, DKIM, DMARC, BIMI · IP and domain reputation · Gmail, Microsoft, Yahoo **Platforms**All major ESPs, no platform migration required **Clients**SaaS, e-commerce, finance, publishing, MarTech, high-volume senders [→ Talk to a deliverability expert](https://meetings-eu1.hubspot.com/lawrence-heslin/site) [More about MailSoar](/about/) [Voir toutes nos études de cas →](/fr/cas-client/) ## Prêt à rétablir votre délivrabilité ?
