Frequently Asked Questions

Yes — all plans include full root access to your dedicated server. You receive SSH credentials at delivery and can connect directly, install additional software, modify configurations, and manage everything independently. We also provide a PowerMTA panel for visual queue management.

Our infrastructure runs from our own datacenter at Tornimae 5, 2nd Floor, 10145 Tallinn, Estonia. Your data is processed under EU jurisdiction, subject to EU data protection law, and you receive a signed GDPR Data Processing Agreement with every plan. CSE OÜ is the Estonian operating entity for all infrastructure services.

You can register with just an email address — we do not require identity verification to sign up. Payment methods including Bitcoin and USDT allow for maximum privacy. We do not share client information with third parties.

Yes. Adding IPs, upgrading server hardware, or moving to a higher plan tier can all be done without data loss. If a hardware upgrade requires a server migration, we handle the full process — migration, reconfiguration, and authentication transfer — with minimal downtime.

Server provisioning and initial configuration: 24–48 hours. Full authentication verification (SPF, DKIM, DMARC, PTR records) and deliverability testing: 3–5 business days. IP warming begins after setup and takes 4–10 weeks depending on target volume.

All plans are month-to-month with no long-term commitment. Cancel at any time — your plan runs until the end of the current billing period. We do not offer refunds on completed billing periods, but you will never be charged for a period you did not use.

Cloud Server for Email has been operating since 2015 — over 10 years of dedicated email infrastructure management. Our team has configured PowerMTA, MailWizz, Acelle Mail, and KumoMTA for clients across the EU, US, and globally. The operational notes archive documents our engineering experience from 2015 to present.

We primarily use PowerMTA (version 5.x) — the industry-standard commercial MTA for high-volume bulk email. We also support KumoMTA and Postfix. The MTA is pre-installed, configured, and tested before delivery. PowerMTA licence is included in managed plans.

PowerMTA 5.x is installed on all PowerMTA plans, kept current with the latest stable release. The PowerMTA licence is included in all managed PowerMTA plans — you do not need to source a separate licence.

We install the current stable release of each application at delivery. Licences for MailWizz and Acelle Mail are included in their respective managed plans. Software updates can be performed by your team or on request as part of managed maintenance.

Yes. We offer installation-only services: PowerMTA 5.x, MailWizz, Acelle Mail, and KumoMTA on external servers you already own or rent. Service includes software installation, DKIM/DMARC/SPF/PTR configuration, and initial deliverability testing. Contact us to discuss your server specifications.

Yes — these are included in every plan, not optional add-ons. We configure SPF authorising your sending IPs, DKIM signing with 2048-bit keys, DMARC policy at p=none for monitoring, and PTR records for all dedicated IPs. Authentication is verified end-to-end before delivery.

We monitor all client IPs 24/7 against major DNSBLs (Spamhaus, Barracuda, Microsoft SNDS). Standard plans include a response within 2 hours of detecting a new listing — we investigate the root cause, submit the delist request, and provide a written incident report. Enterprise plans include a 1-hour SLA.

Yes. Additional IPs can be added to any plan at any time. Each new IP requires a warmup schedule — we configure this as part of the IP addition process. Contact us to discuss IP allocation and pricing for your volume tier.

Yes. KumoMTA is a modern open-source MTA with comparable features to PowerMTA and no commercial licence cost. We configure and manage KumoMTA deployments on request, particularly for high-volume deployments where PowerMTA licensing cost is a factor.

Yes. Domain reputation at Gmail and Yahoo is tied to your sending domain, not your IP or ESP. If you keep your sending domain, existing domain reputation transfers to the new infrastructure. However, IP reputation does not carry over — new dedicated IPs require a 4–10 week warmup period from scratch.

Yes. IP warming is included in all infrastructure plans. We build a per-ISP warmup schedule based on your target volume and list quality before the first send. We monitor Gmail Postmaster Tools, Microsoft SNDS, and complaint rates throughout, and adjust the schedule based on ISP signals.

Gmail begins reducing inbox placement above 0.08% complaint rate, with active enforcement above 0.10%. Yahoo TS02 deferrals begin around 0.10%. Our FBL processing auto-suppresses complainants within seconds. We target below 0.05% on well-managed lists.

Yes. Our infrastructure is configured to comply with Gmail and Yahoo's February 2024 bulk sender requirements: full SPF/DKIM/DMARC authentication, one-click List-Unsubscribe headers, and complaint rate monitoring. These are the baseline requirements for reliable inbox delivery at all major providers.

Yes — our Cold Email Infrastructure plan is purpose-built for B2B outreach. Cold email must run on separate domains and IPs from your primary sending domain. Our cold email plans include isolated domain pools, automated warmup, and domain rotation to protect your primary brand domain's reputation.

Domain rotation spreads cold outreach across multiple sending domains (e.g. yourbrand-sales.com, yourco-outreach.com) rather than sending from your primary domain. If one domain gets flagged or throttled, only that domain is affected. Our cold email plans include 3–20 domains depending on tier.

We accept credit card (via PayPal), PayPal, Bitcoin, and USDT. All prices are in euros. We do not accept SEPA bank transfers or wire transfers. No setup fees — billing begins when your infrastructure goes live.

No. The monthly plan price is all-inclusive. For one-time services (IP warming engagement, installation-only services), pricing is quoted per project with no recurring fee.

All prices are in EUR. For clients paying with Bitcoin or USDT, the EUR equivalent is calculated at the exchange rate at the time of payment.

EU businesses with a valid VAT number are invoiced without VAT (reverse charge mechanism). EU individual customers may be subject to VAT. Provide your VAT number when signing up to ensure correct invoicing.

Yes. A signed GDPR DPA is included with every plan at no additional cost. Our infrastructure operates from our own datacenter in Tallinn, Estonia, under CSE OÜ, the Estonian operating entity. The DPA covers sub-processors, data transfer mechanisms, security measures, and deletion obligations. Available for review before signing up.

All servers operate within EU jurisdiction (Estonia). Bounce data, FBL complaint reports, and subscriber data never leave EU infrastructure. This eliminates the need for Standard Contractual Clauses for EU personal data — your data stays in the EU end-to-end.
