Handing clients verified rows? Read this first

Your deliverable is a list a client can act on, and the sending side is what proves the rows work. Mail Pro carries a prospect through a multi-step sequence on a schedule you set, so the first touch and the follow-ups leave from the same place. That keeps the thread attached to the contact you sold.

Rotation and warm-up matter when you are sending on behalf of several clients at once. You spread volume across sending addresses and let new ones build reputation before they carry a large batch. That is the part a spreadsheet cannot do, and it is why contractors look past a plain contact database.

Everything then collects in one reply inbox, which is where a contractor earns repeat work. A prospect who answers lands in the same view as the rest of the campaign, and open, click and reply tracking tells you which sequences produced conversations rather than silence. You pass on behaviour, not guesses.

Onboarding is the first thing to weigh. The entry tier pairs the lifetime licence with set-up help, which suits a contractor who has not run cold sequences before and wants the campaign structure checked. The second tier trades that attention for two mailboxes, so you gain a second sending address.

Two mailboxes changes your rotation headroom. If you run campaigns for more than one client, a single address means every campaign shares one reputation, and a poor batch from one client touches the other. A second mailbox lets you separate them, provided you warm it properly before it carries volume.

Neither tier hands you the prospect data. You still source and verify the rows yourself, then import them and map the fields the sequence needs. Budget your own time for that step, because Mail Pro organises and sends what you bring rather than finding contacts on your behalf.

The worry is a row you cannot defend when a client asks where a name came from. Mail Pro tracks what happens after a send, so reply, click and open activity gives you evidence a campaign ran. It does not vouch for the contact record itself. Keep your own source notes beside every row you deliver.

Open tracking deserves a plain caveat. A recipient's mail client may block images, so an open can happen and never register. If you report opens to a client, say what the number represents and lean on replies as the firmer signal of interest.

Volume is the other place to be careful. A fair use condition sits behind the unlimited element, so read that wording before you promise a client a large weekly send. Your sending provider also sets its own ceilings, which rotation cannot lift. Plan around those caps rather than against them.

Compare the two tiers by counting the clients you serve at once. One mailbox keeps everything on a single reputation, which is workable for a contractor running one campaign at a time and happy to learn the set-up from the documentation. Onboarding suits that position.

If two clients send in the same week, the two-mailbox tier gives each campaign its own sending identity. That separation is worth more than the onboarding help once a second client is paying you, because one client's poor list no longer drags the other's deliverability down with it.

Decide before you buy, not after. Write down how many mailboxes your current clients need, add one for growth, and match that to a tier. Then confirm the fair use wording and your provider's caps, so the volume you plan is the volume you can actually send.
