We are looking for an experienced **Email Deliverability Specialist / Mailing Infrastructure Consultant** to support us long-term with building, operating, and optimizing a scalable email sending solution. Our goal is to build a reliable solution for sending business emails. This includes especially **invoices, payment notifications, payment reminders, debt-collection notices, and other business-related transactional emails**. We want to reach a stable sending volume of approximately **10,000 emails per day**. For us, it is not only important that the emails can be technically sent, but also that they are accepted and delivered as reliably as possible by major mailbox providers such as **Gmail, Outlook, Yahoo, and others**. ## Our Goal We are looking for someone who can give us a realistic assessment of: * how this sending volume can be achieved technically and sustainably * what kind of infrastructure would make sense * which providers would be suitable * what risks exist regarding deliverability, reputation, spam placement, and provider suspensions * how deliverability can be monitored and improved long-term * how quickly a volume of around 10,000 emails per day can realistically be achieved It is important to us that we receive an honest technical assessment and a clear plan, not generic promises. ## Desired Experience The candidate should have experience with **high-volume email sending**, **SMTP infrastructure**, **deliverability**, **IP/domain reputation**, and the behavior of major mailbox providers. Experience with offshore or specialized hosting companies is especially interesting to us, particularly with providers such as: * **Shinjiru** * **AlexHost** * **AbeloHost** * comparable offshore VPS or dedicated server providers * specialized hosting providers for larger mailing infrastructure We want to understand which providers are suitable for our goal, what their advantages and disadvantages are, and which solution would be the most stable in the long run. ## Project Description We are planning to build an email sending solution for business communication with a higher daily volume. The candidate should not only advise us at the beginning, but ideally also support us long-term. This includes strategy, implementation recommendations, monitoring, optimization, and ongoing technical consulting. We do not want to dictate every technical detail in advance. The specialist should explain which approach makes the most sense based on their experience. ## What We Expect from the Candidate The candidate should explain: 1. Whether our goal of approximately **10,000 emails per day** is realistically achievable 2. In what timeframe this volume could be reached in a stable way 3. What kind of infrastructure would be suitable 4. Whether offshore providers such as **Shinjiru, AlexHost, or AbeloHost** are suitable 5. Which providers they would specifically recommend and why 6. What risks exist with Gmail, Outlook, Yahoo, and other mailbox providers 7. How they would achieve high deliverability and the best possible inbox placement 8. How they would handle bounces, spam placement, blocks, throttling, or poor reputation 9. What monthly infrastructure costs would be realistic 10. What kind of ongoing support is necessary to keep the system stable ## Our Current Idea Based on previous discussions, we currently see the following as a possible direction: * using multiple servers/IPs instead of only one single server * using multiple domains or subdomains * using a provider such as Shinjiru as the main solution * using AlexHost or comparable providers as a backup or additional solution * building proper technical authentication and reputation * gradually scaling the sending volume * continuously monitoring deliverability and reputation These points are only an initial idea. We want the specialist to tell us whether this approach makes sense or whether there are better alternatives. ## Long-Term Cooperation We are not only looking for someone for a one-time setup. Ideally, we are looking for someone who can **support us long-term**. Long-term support may include: * ongoing deliverability monitoring * optimization of the sending strategy * adjustments when issues occur with Gmail, Outlook, Yahoo, etc. * consulting for scaling * evaluation of new providers * technical troubleshooting * improving inbox placement * monthly checks of reputation, bounces, and blocks * fast support in case of deliverability problems Our goal is to build a stable partnership with someone who has real experience and can accompany this project technically on an ongoing basis. ## Important Questions for Applicants Please answer the following questions in your application: 1. Have you already managed projects with approximately **10,000+ emails per day**? 2. What experience do you have with **Shinjiru, AlexHost, AbeloHost**, or similar offshore hosting providers? 3. Which providers would you recommend for our goal? 4. What inbox rate is realistic after 1 week, 2 weeks, and 4 weeks? 5. How would you generally approach reaching the target volume in a stable way? 6. What risks do you see with debt-collection/payment-reminder emails? 7. What monthly infrastructure costs would you expect approximately? 8. What ongoing tasks would be necessary after the initial setup? 9. Can you support us long-term? 10. Have you successfully completed similar projects before? ## What We Can Provide We can provide: * domains * desired daily sending volume * information about recipient structure * email templates * infrastructure budget * access credentials after agreement * contact person for questions * long-term cooperation if the initial work is successful ## Budget We are open to proposals. As a rough orientation, a setup budget of approximately **$600 USD** has previously been discussed, in addition to monthly infrastructure costs of around **$100–200 USD**. However, we are willing to review realistic offers if the proposed solution is technically sound, stable, and suitable for long-term operation. ## Project Goal The goal is not simply to send a large number of emails technically. Our real goal is to: * reliably deliver approximately **10,000 business emails per day** * achieve the best possible inbox placement * build a stable sending reputation * minimize outages, suspensions, and spam-related issues * have a solution that is supported long-term * work with an experienced specialist who can honestly assess what is realistic We are looking for someone who does not just set up a system once, but who can help us build and maintain a professional, stable, and scalable email deliverability solution over the long term.

Hi, For your target of ~10,000 transactional emails/day with Gmail, Outlook, and Yahoo inbox placement in mind, are you planning to send only fully opted-in transactional emails or will some flows include overdue/payment reminder sequences with higher complaint risk? Building scalable mailing infrastructure with stable deliverability is not just about sending volume — it’s about reputation management, warm-up strategy, authentication, routing, and ongoing monitoring. I can help you structure a long-term setup that focuses on inbox placement, provider stability, and minimizing throttling or suspensions. My approach would include: Multi-server/IP architecture with gradual warm-up and traffic distribution Dedicated sending domains/subdomains with SPF, DKIM, DMARC, rDNS, and reputation isolation Deliverability monitoring across Gmail, Outlook, Yahoo, and Microsoft SNDS/Postmaster tools Bounce, complaint, suppression, and retry handling strategy Reputation management and inbox-placement optimization over time Provider evaluation for long-term stability, including offshore and specialized infrastructure options Clear scaling roadmap instead of risky volume spikes Best regards, Hafiz Anas

Hi, I can support you on this project as an email deliverability and infrastructure specialist. I have experience designing and managing SMTP based systems for high volume transactional sending including invoices, payment alerts, reminders, and system notifications at scale around and above 10,000 emails per day. My approach is always focused on long term inbox placement rather than just sending volume. I work with proper domain and IP warm up strategies, SPF DKIM and DMARC alignment, bounce and complaint handling, reputation monitoring, throttling control, and provider specific behavior across Gmail, Outlook, and Yahoo. For infrastructure, I typically evaluate providers based on deliverability stability rather than offshore branding, and recommend a setup using reputable SMTP services or dedicated servers with strong reputation control instead of risky or unstable hosting environments. I can also advise clearly on whether multiple IPs, subdomains, or hybrid routing is actually needed for your case. I can assess your current idea, design a scalable sending architecture, estimate realistic inbox rates over time, and outline costs and risks in detail. Long term support for monitoring, optimization, and troubleshooting is also available. I have handled similar deliverability focused projects and can guide you with an honest technical plan rather than generic advice. Best regards, Moiz

I have specialized in stabilizing transactional email pipelines for platforms where critical alerts—like MFA and billing notifications—must hit the inbox within seconds. Having navigated deliverability crises for high-volume senders, I understand that success depends on precise alignment between your sending infrastructure and the evolving filtering algorithms of ISPs like Google and Microsoft. I recently helped a SaaS client move from a 40% junk-folder rate to a 99% inbox placement by re-engineering their IP strategy and authentication layers, ensuring their transactional flow remained uninterrupted during high-growth phases. I will start with a comprehensive audit of your DNS configuration—specifically hardening SPF, DKIM, and DMARC policies to build immediate trust with receiving servers. I'll perform a deep-dive analysis of your sender reputation using Google Postmaster and SNDS to identify specific delivery bottlenecks or blacklisted subnets. Next, I will optimize your mailing headers for the latest 2024 sender requirements, implement feedback loops for complaint monitoring, and ensure your "List-Unsubscribe" headers are correctly formatted. I will also assess your throughput to ensure your warming schedule matches your volume without triggering ISP rate limits or temporary deferrals. Are you seeing specific SMTP error codes, or are emails simply being diverted to the "Junk" folder without a bounce? Also, have you recently changed your ESP or increased your sending volume significantly? I am available for a quick chat or a brief call to review your current setup and outline a technical roadmap to restore your deliverability. Let’s connect to ensure your critical emails reach your users reliably.

Hi, I can help you build and maintain a highly deliverable, scalable mailing infrastructure. Here are direct answers to your evaluation points: 1. Experience: Yes, I have managed infrastructure handling 10K+ daily transactional emails. 2. Offshore Providers: Familiar with Shinjiru and AlexHost. Using multiple VPS/IPs with rotation and proper IP failovers is the right strategy for transactional stability. 3. Timeline & Delivery: Week 1-2 will focus on warming up subdomains/IPs. A safe 90%+ inbox placement rate is achievable by Week 4 with strict volume scaling. 4. Risk Management: Debt-collection notices carry higher spam-report risks. I will mitigate this by configuring strict authentication (SPF, DKIM, DMARC) and feedback loops (FBL). 5. Cost: Your $600 setup and $100-$200 monthly budget are realistic for a multi-IP, multi-domain system. I am ready to handle technical troubleshooting, blacklists, and ongoing monitoring for a long-term partnership. Let's discuss your templates and get started! Best regards, Tanjirul
