Re: Do you also work with people who don’t use MailSenpai?
Yes. Consulting concerns your domain, your servers and the way you send, whatever platform you use. If at some point MailSenpai or SMTP Senpai could be useful to you I will tell you, but it is not a condition.
Re: Can you guarantee that my emails reach the inbox?
No, and I would be wary of anyone who promises it. The final decision lies with Gmail, Outlook and the other providers. What I can do is remove the known technical causes, put authentication and reputation in order and give you a way to measure how your emails arrive.
Re: How does a consultation work?
Remotely and in writing, by email. The first reply is free and tells you whether and how I can help. Then we start with the deliverability analysis, which is paid and begins only after you have accepted a written proposal. From there, if needed, we work step by step with checks on real sending.
Re: Do you need the passwords to my systems?
Not to begin with. A lot can be understood from public DNS records, from the headers of an email and from the reports you already receive. If access is needed later, we agree on it and I prefer it read-only.
Re: How much does it cost?
It depends on the scope, an analysis is not an infrastructure to build. The first reply is free, then you receive a written proposal with activities, timing and cost, before we start. No commitment until you accept it.
Re: Do you also work on in-house sending servers?
Yes. I design and configure high-performance SMTP relays and MTAs on Linux servers, with DNS, bounces, feedback loops and monitoring, and I leave your team the documentation to manage them.
Re: Do you also help with sending to purchased lists?
No. I only work with contacts collected in line with the rules and I do not help anyone get around filters. It is also the safest way to protect your domain.
