Choosing a mailbox service when your client needs sourcing proof

Your money goes towards mailboxes you can sign into and configure, not towards rows of data. LocalSMTP provides standard SMTP and IMAP access so you can connect the mailboxes to the tools you already run, and it includes browser webmail for the times you need to check a thread or a reply without opening a client.

Consider what that means for a contractor handing lists to clients. You get a sending and receiving identity per mailbox, and you get warm-up and authentication checks that help you confirm a mailbox is set up correctly before you put traffic through it. Those checks are about configuration, so they support the part of your work where a client asks whether the setup is sound.

Pricing follows the lifetime tiers rather than a monthly subscription, and the tiers are counted in mailboxes. That structure suits contractors who run several client accounts at once and want a predictable number of identities to allocate. The tier you pick should reflect how many separate client relationships you expect to serve, not how many contacts you hope to deliver.

Tier boundaries sit at mailbox counts: Starter covers five mailboxes, Studio covers fifteen, and Floor covers fifty. The decision for a lead-generation contractor is therefore an allocation question. Count the client accounts you serve, decide how many separate mailboxes each one needs, and add a margin for accounts that grow during the year.

Five mailboxes suits a contractor with a small number of accounts who can share a mailbox across related work. Fifteen fits a practice where several clients each want their own identity and you want room to separate outbound threads from reply handling. Fifty is for a operation running many client accounts at once, where a single shared mailbox would blur who owns which conversation.

The source for these tiers is the lifetime pricing table published on softwareprogrammer.app. Read that table before you commit, because the mailbox count is the only thing that changes between tiers. Everything else in the product, including the browser webmail and the warm-up and authentication checks, is part of what you are buying rather than a tier-specific extra.

The hesitation is usually about proof. A contractor who delivers lists to clients is judged on whether each row can be traced to a source, and no mailbox product supplies that trace. LocalSMTP gives you mailboxes, so it supports the conversations and the verification work around a list, but it does not create the list and it does not vouch for the contacts inside it.

Be clear with yourself about the boundary before you pay. A mailbox is not a contact list, and nothing in the product turns a mailbox into one. If your client asks where a row came from, the answer has to come from your own sourcing process, not from the mail tool you use to reach out. That distinction protects the client relationship you are worried about.

Inbox placement is the other area where expectation can outrun the product. Delivery to a recipient's inbox is not guaranteed by any mailbox service, and LocalSMTP is no exception. Warm-up and authentication checks help you put a mailbox in good order before you send, but they describe setup rather than a promise about where a message lands.

Take a contractor serving three clients who each want one mailbox for outreach and one for replies. That is six mailboxes, which sits above Starter and inside Studio. Studio gives the contractor fifteen mailboxes, leaving room to add accounts or split a client's sending and reply handling without buying another tier. The fit is about headcount of mailboxes, not about volume of contacts.

Now take a contractor running a larger book of client accounts, where each account expects its own identity and the contractor wants replies kept apart. Floor covers fifty mailboxes, which allows many separate client identities plus spares for accounts that pause and restart. Neither worked example says anything about list quality, because the tier only decides how many mailboxes you can run.

In both cases, connect the mailboxes over SMTP and IMAP to the tools you already use, and use the browser webmail for spot checks. Run the warm-up and authentication checks before you start sending on a new client's behalf. If you need anything beyond the mailboxes, note that extra services are priced separately from the lifetime tier.
