Frequently asked questions

What is email deliverability?

Email deliverability is the ability of your emails to reach recipients' inboxes instead of getting flagged as spam.

How does Apollo improve email deliverability?

Apollo automatically handles domain and mailbox warm‑up, monitors inbox placement, and protects sender reputation—without a separate tool.

Do I need a separate warm‑up tool?

No. Apollo includes a built‑in warm‑up engine that works automatically for new sending domains and mailboxes.

Deliverability that fuels pipeline growth

Apollo brings your deliverability stack under one roof. No patchwork of extra tools required. Purchase and authenticate new domains, add mailboxes, warm them up automatically, and monitor inbox placement in real time.

Some services (like domain and mailbox purchases) come with a cost, but everything is built into Apollo so you get a simpler, more affordable, all-in-one solution compared to buying separate tools.
