Choosing mailboxes without paying twice

Your campaign brief is signed off, the copy is written, and the send fails on a mailbox nobody set up properly. That is the moment a marketing manager starts looking at alternatives, not because the current tool is wrong but because the channel needs addresses you can configure, sign into and keep.

The purchase here gives you standard SMTP and IMAP mailboxes you can open in browser webmail as well as a mail client, with warm-up and authentication checks alongside setup. You are paying for working mailboxes rather than a second analytics layer, so the value question becomes whether your channel needs sending identities or more reporting.

Because the tiers are lifetime and divided by mailbox count, the cost is easier to reason about than a recurring seat. You count the identities the agreed channel actually uses, match that number to a tier, and treat anything outside the mailbox count as a separate decision rather than part of the deal.

Three published tiers sit on softwareprogrammer.app: Starter with five mailboxes, Studio with fifteen, and Floor with fifty. The line between them is simply how many sending identities you need, not features that open at higher levels. For a single channel run by one manager, that count is usually the whole decision.

Start by listing the addresses your agreed channel uses: the person sending, any shared team inbox, and the aliases you test from. If that list sits at five, Starter covers it and you stop there. Moving to Studio buys more mailboxes, not better placement, so the upgrade should answer a count problem rather than a wish for more.

Floor exists for cases where the channel genuinely runs many identities at once. Nothing in the published tier structure suggests the larger purchase improves delivery or reporting, so a manager who cannot name the extra addresses in advance should read the table again before paying for headroom they will not use.

Before you pay, read the published table slowly and separate the mailbox count from everything beside it. The warm-up and authentication checks help you set up properly, but they are a setup aid rather than a promise about where messages land. Knowing that in advance keeps your expectations honest when first results come back.

Then check your own side of the work. A tier supplies mailboxes, not people to write to, so your audience list stays your own research and your own responsibility for consent and relevance. If the channel plan assumes the tool brings contacts, fix the plan before fixing the subscription.

Finally, ask what sits outside the tier. Extra services beyond the mailbox count are priced separately, so a quiet assumption that they come included can turn a single lifetime payment into several. Write down what you need, match each item to the published table, and take only the parts your channel will use.

Suppose you currently pay for a sending platform and a separate inbox tool, and your objective is measurable output from one channel. Adding LocalSMTP as a third subscription would duplicate what exists, so the honest move is to replace one of them, not to stack it alongside both.

Work it through with numbers on paper. Count the sending identities the channel needs, compare that to the five, fifteen and fifty mailbox tiers, and note which existing tool the mailboxes would replace. If the count fits Starter and the replacement is clean, the decision is small and reversible in effort terms.

If the count climbs mid campaign or the channel splits into several identities, moving from Starter to Studio is a count change, not a strategy change. Keep the published table open while you plan, and let the number of addresses drive the tier rather than the other way round.
