FAQ
Emails fail, get rejected, or show SMTP and authentication errors.
I configure your SMTP and email delivery environment, connect the selected provider, authenticate your sending domain, and test the required mail flow. You receive a working technical setup ready for legitimate transactional or business email communication after completion.
A business or developer needs an email provider connected correctly.
This service is suitable for businesses, SaaS teams, agencies, developers, and website owners who need SMTP or email delivery infrastructure configured. I can connect a supported provider to your domain and application environment and configure the required technical settings.
Multiple providers, domains, or applications require a larger implementation.
Premium is recommended when your project involves multiple sending providers, domains, applications, APIs, or advanced technical requirements. I handle the wider implementation, perform end-to-end testing, provide documentation, and include seven days of reasonable post-delivery support.
The buyer does not know which records or credentials are required.
Depending on your provider and project requirements, I can configure SMTP credentials, API connections, SPF, DKIM, DMARC, DNS records, sender identities, domains, and testing environments. The relevant sending connections are checked after configuration before delivery.
