An SMTP mailbox service alternative for a first honest test

Picture a founder who has paid for a sending plan and discovered, three weeks in, that no reply has arrived and the contract runs to the end of the year. The alternative is to stand up a handful of real mailboxes first, send from them yourself, and treat replies as the signal that decides what you buy next. That is the shape of the decision here.

With LocalSMTP your money goes towards working mailboxes rather than a promise about volume. You get standard SMTP and IMAP mailboxes, browser webmail for whoever prefers signing in through a tab, and warm-up and authentication checks to run alongside setup. The lifetime tiers are counted in mailboxes: Starter holds five, Studio holds fifteen and Floor holds fifty.

Your outlay therefore scales with how many people or addresses you need to send from, not with how many messages you hope to push out. For a first test that is the right variable to control. The tiers are published on softwareprogrammer.app, so you can read the mailbox counts against your plan before anyone signs anything.

Five, fifteen or fifty: the tier boundaries here are drawn by mailbox count alone. A two-person founding team testing one offer sits comfortably in Starter. Once several people need their own mailboxes, or separate addresses for different offers, Studio becomes the natural step, and Floor only makes sense when the sending roster has grown well beyond a test.

Nothing in the tier removes the need for your own list. You still research every address you write to, because the mailbox gives you a place to send from and nothing more. Budgeting should therefore include your time for building that list, not just the one-off payment for mailboxes.

Anything outside the mailbox count, including extra services, is priced on its own, so the published table is the document to read line by line. Say yes to a mailbox count you can fill with real work, and leave the rest until replies justify it.

Before paying, settle three questions. First, how many mailboxes will genuinely be used in the first month, since the tiers are sold by count. Second, who will manage the warm-up and authentication checks, because those require attention at the start. Third, whether anyone can send from the mailboxes through a normal mail client as well as webmail.

Then decide what counts as a result. A startup testing outreach should write down the number of sends and the number of replies expected before any message goes out, so the outcome is judged against a written target rather than a feeling around the fourth week. That discipline matters more than which tier you pick.

Finally, check expectations about delivery. Placement in the inbox is not something a tier can promise, so plan for some messages to sit elsewhere even after the checks pass. A mailbox count does not supply recipients, and services beyond the count carry separate prices. Read the published table, confirm the extras you need, and only then pay.

A practical path runs in two steps. Begin on Starter with the people who will actually send, set up the warm-up and authentication checks, and run your limited test for long enough to see whether replies happen at all. Only if replies appear does the next question arise: more mailboxes, or more extras?

When you move up, the decision stays simple because the tiers differ by count. Studio covers fifteen mailboxes, which fits a team that has added senders or split its offers into separate addresses. Floor covers fifty and belongs to a later stage, when outreach has become routine rather than experimental.

Treat each step as a response to evidence rather than anticipation. The lifetime structure removes renewal pressure, but the mailbox count is still the thing you are paying for, so move up only when you can name the senders who will use the new mailboxes. If you cannot name them yet, the current tier is doing its job.
