Email deliverability optimization
We comprehensively improve email deliverability: authentication, domain/IP reputation, base hygiene, content, monitoring of spam metrics and blocklists. Honestly and bluntly upfront: we reduce landing in spam and increase the chances of the inbox, but the inbox is NOT guaranteed — spam filters, reputation, content and recipient complaints decide, which we do not fully control. And honestly: deliverability ≠ opens ≠ sales; a clean legal base is needed. Without promises of the inbox and sales.
Email deliverability optimization — overview
Email deliverability optimization is comprehensive work on landing in the inbox: an audit of authentication (SPF/DKIM/DMARC), domain/IP reputation and sending history, base hygiene (validation, removing inactive/invalid, working with complaints and unsubscribes), content optimization (anti-spam triggers, text/image balance), segmentation and frequency, monitoring (postmaster tools, blocklists, spam placement tests), a remediation plan. The work: audit, fixes, hygiene, monitoring. Honestly about 'we reduce the spam risk but the inbox is not guaranteed', this is key: we eliminate technical and behavioral causes of landing in spam and increase the chances of the inbox, but the inbox cannot be guaranteed — the final decision is made by mail providers' spam filters based on reputation, content, engagement and complaints, which we do not fully control. 'We guarantee the inbox/X% deliverability' = a lie. Honestly about 'deliverability ≠ opens ≠ sales': even perfect delivery does not equal opens, and opens — sales; they depend on the base, offer, product. Honestly about 'a clean legal base is needed', this is critical: the main cause of poor deliverability is a bad/unsolicited base (complaints, spam traps). We clean the base and will honestly say if the problem is in its legality/quality; a mailing to a bought/leaked base cannot be technically 'cured'. Honestly about 'open rate is distorted': open metrics are inaccurate (Apple Mail Privacy, etc.) — we honestly account for this. Honestly about 'a process, not a one-time fix': reputation and deliverability recover gradually. Honestly about the effect: it comprehensively improves deliverability (authentication, reputation, base hygiene, content, monitoring), reducing landing in spam, but the inbox is not guaranteed (filters/reputation/complaints decide); deliverability ≠ opens ≠ sales; a clean legal base is needed; this is a process. Honestly about access: access to the ESP/domain/statistics, readiness to clean the base are needed. An important boundary: this is deliverability (infrastructure/hygiene); authentication — 537; warming — 539/540; campaigns — 541-552. The base price starts from 25,000 ₽ for audit/optimization (depends on the state).

FAQ
Do you guarantee the inbox/a deliverability percentage?
No, honestly: we eliminate spam causes and increase the chances of the inbox, but the final decision is made by providers' spam filters based on reputation, content, engagement and complaints, which we do not fully control. 'We guarantee the inbox/X% deliverability' is a deception. We reduce the risk, without a guarantee of the inbox.
Does good deliverability = sales?
No, honestly: even perfect delivery does not equal opens, and opens — sales; they depend on the base, offer, content, product. Plus open rate is distorted (Apple Mail Privacy, etc.). We honestly improve deliverability as hygiene, without promises of sales.
What if the base is bought/unsolicited?
Technically it cannot be cured, honestly: the main cause of poor deliverability is a bad/unsolicited base (complaints, spam traps), and a mailing to a bought/leaked base cannot be saved by settings. A legal base with consent (152-FZ) is needed. We will honestly say if the root is in the base and will not undertake to 'cure' spam.
