Before you sign another monthly mail contract, read this

You send a careful note to the person who signs off, wait a week, hear nothing, and later find the message sitting in a spam folder while the contact form went through. That gap between effort and reply is where a monthly mailbox contract starts to feel expensive, because the invoice keeps arriving whether or not the work does.

With LocalSMTP the maths runs the other way. You pay once for a set number of standard SMTP and IMAP mailboxes, open them in a browser or a mail client, and use the warm-up and authentication checks to get setup right. The tiers are published as Starter with five mailboxes, Studio with fifteen and Floor with fifty, so you can match a count to how many client conversations you actually run.

For a freelancer chasing two or three new clients a month, that one-off shape removes the recurring line from your books. The tier you pick has to fit the number of separate mailboxes you want, since the count is the unit of purchase. Price details for each tier sit in the publisher's own table, which is where you should read them.

Five mailboxes, fifteen or fifty. That is the decision, and it hinges on how you keep work apart. A freelancer with one trading name and one follow-up habit may only need a few boxes. Someone running separate addresses per service, plus a booking address and a personal one, drifts towards the middle tier without noticing.

The dividing line is not about sending volume, because nothing in the tiers is sold by the send. It is about how many sign-ins you want to manage. Each additional mailbox is another place to check replies, another signature to keep current, and another address to warm up before you trust it with a client pitch.

Compare the tier counts against the addresses you already use, not against an imagined future business. If you can name the mailboxes you would fill this month, you have your tier. If you cannot, the smaller tier is the honest choice and the larger one can wait until the work justifies it.

Start with the mailboxes themselves. You should be able to confirm that the tier gives you standard SMTP and IMAP access, that webmail opens in a browser, and that the warm-up and authentication checks are part of what you are buying rather than an add-on you find out about later. Read the published tier list and match the mailbox count to your own addresses.

Then look at the workflow around it. Your outreach depends on knowing who to write to, and the product does not supply that. Confirm you are comfortable sourcing your own contacts and keeping them current, because a mailbox holds conversations, not a list of prospects waiting to be written to.

Finally, price the extras. Some services that sit alongside the mailbox count are sold on their own terms, so check the table for anything you assume is included. Ask directly which parts of your intended setup fall inside the tier and which do not, before you commit to a purchase.

If you begin on Starter and later need more addresses, the move to a larger tier depends on what the publisher allows. Ask whether an upgrade credits what you already paid or charges the full price of the new tier, because that answer decides whether starting small is cheap or merely deferred. Get it in writing before you buy the first tier.

The practical route is to start where your current address count sits, run a month of outreach, and watch which mailboxes earn their keep. A box that only receives newsletters is a candidate for closing. A box that produced a signed-off project is the reason to stay. That observation is more useful than any forecast.

When you do move up, keep the warm-up and authentication checks in your routine rather than treating them as a one-time task. New mailboxes need the same treatment as old ones, and the checks only tell you what has passed, never what will land. Build the habit into the week you already spend on admin.
