Plunk

one price, one tenth of a cent an email, no tiers and no contact games — and no discount however much you send.

$10/mo#small-senders-who-value-

the most transparent pricing in the category by a distance, and the linearity that makes it honest at ten thousand makes it expensive at a hundred thousand.

$0.001 per email, no monthly fee, unlimited contacts, and both transactional and marketing sends at the same rate. there are no tier cliffs, no contact-count arithmetic and no plan to outgrow. after reading nine other pricing pages, the clarity is genuinely striking.

the flip side is that the line never bends. a hundred thousand emails costs exactly ten times ten thousand — $100 — which is more than mailgun, sendgrid, smtp2go, resend, mailersend and amazon ses charge for the same volume. that is by design rather than omission, but it means plunk is a small-sender product whatever its scaling story says.

the description above is ours, condensed from the ranking. pricing moves — check it on the vendor's own page before you rely on it.

our verdict

the most transparent pricing in the category by a distance, and the linearity that makes it honest at ten thousand makes it expensive at a hundred thousand.

we researched this category against vendors' own pricing pages and licence files. that is where this line comes from — not from the vendor, and not from anything they paid for.
