Questions businesses are asking

Straight answers on cost, visibility, timing and what the work involves.

Can we keep our email addresses when moving providers?

Usually, when the business controls its domain and the destination supports the addresses required. We list user mailboxes, shared addresses and forwarding arrangements before a move. Message history, calendars and contacts are assessed separately so you know what can be transferred.

Why can we send email but not receive it?

The receiving service, domain routing or mailbox may be the problem. A recent provider or domain change is useful evidence. We check the affected addresses and delivery errors, then test incoming messages and website forms after an agreed correction.

Why do our messages go to spam?

The investigation can include whether legitimate senders are recognised by the domain, how messages are sent and any rejection or filtering evidence available. We explain the specific findings before changing settings. Correct setup helps, while the receiving provider still controls its filtering.

What information do you need before quoting?

Send the domain name, current email provider, approximate user count and a description of the issue or move. Include an error message with private details removed if available. Passwords and account access are arranged securely after the work is agreed.

What happens at handover?

We test the addresses and functions included in the work, confirm who controls the accounts and explain any remaining actions. Subscription charges, continuing support and any data that could not be moved should be clear before the old service is closed.
