FAQs

My open rates are continuously going down and my emails land in spam. How can you help?

Delivery problems stem from various factors that require proper analysis. An email deliverability audit identifies the underlying issues - authentication gaps, reputation problems, content triggers, or infrastructure faults - and gives you a prioritised fix list.

Can Postbox Services provide us consultancy while we do our own stuff?

Yes. We work as external consultants or auditors, assisting your internal teams in managing email delivery themselves. We train, advise, and review without needing to take over your operations.

What is the best open/click rate Postbox Services assure?

Rates depend on your list quality, industry, content, and sending history. No honest consultant guarantees specific numbers. What we guarantee is a thorough audit, actionable recommendations, and measurable improvement in deliverability metrics.

We are looking to build email infrastructure which can handle few million emails daily. Can Postbox Services help?

Yes. We design and build sending systems at any scale - from startup outreach setups to enterprise-grade platforms handling tens of millions of messages per day.

Where can I host my email infrastructure?

It depends on your volume, compliance requirements, and budget. We evaluate options including AWS SES, dedicated SMTP providers, self-hosted MTAs, and hybrid setups - and recommend the right fit for your specific situation.
