No subscription · No monthly minimum

Pay only for messages that actually arrive.

SMS, MMS and email, billed per segment at the carrier's own count. If a message doesn't arrive, the charge comes back. Every credit and every charge sits on a ledger you can read line by line.

What one campaign actually cost

Estimate held2,400 recipients, reserved before sending	−$36.00
Hold releasedat completion, in full	+$36.00
Sent2,317 messages, priced at the segments the carrier reported	−$34.76
Suppressed83 recipients had opted out. Never sent, never billed	$0.00
Refunded11 messages the carrier could not deliver	+$0.17
Charged	−$34.59

That's the shape of a real bill. Most platforms charge the estimate and keep the difference. We charge what the carrier charged for, and give back what didn't land.

Pricing

One rate per channel. No tiers, no feature gates, no monthly floor. SMS is billed per segment, so a long message costs more than a short one, and the composer tells you before you send rather than after.

Channel	Billed	Rate
SMS	per segment	$0.0150
MMS	per message	$0.0450
Email	per message	$0.0030

What it does today

Listed honestly. Anything marked soon is being built and isn't in your account yet.

SMS, MMS and email

One contact list, three channels. Send now or schedule it, with consent checked per channel at the moment of sending.

Contacts and lists

Import by CSV. Numbers are normalized and validated on the way in, so a malformed number is caught at import rather than at send.

Delivery receipts

Carrier-level delivery status per message, not just "we handed it off". Failures are recorded with the carrier's own reason code.

Auditable billing

An append-only ledger. Every credit, hold, charge and refund is a permanent line item, and your balance is the sum of them.

Branded short links

Links on our own domain, not a shared public shortener. Shorter links mean fewer segments, which means a cheaper send.

Quiet hours

Set a window per account. A campaign scheduled inside it waits until the window opens, in your recipients' local time.

Click tracking soon

Per-recipient click attribution. The links and the recording already work; the reporting screen doesn't yet.

Automation flows soon

Sequences with delays and triggers. Not built. When it ships it'll be listed here without this tag.

Segment builder soon

Targeting by contact attributes. Today you target by list.

Consent is enforced, not suggested

The expensive mistake in messaging is sending to someone who asked you to stop. Wally is built so that's hard to do by accident.

Opt-outs are exact

STOP, END, CANCEL and the rest are matched exactly against the message. Someone who writes "please don't stop sending these" stays subscribed.

One suppression list

An opt-out is recorded against the phone number or email address, and every send path checks the same list. There's no second place for it to be missed.

Bounces suppress automatically

A hard bounce or a spam complaint adds the address to the suppression list without anyone having to notice.

Consent keeps its evidence

Each record stores when consent was given, through what, and what the proof was. That's what you need when someone asks.

Questions

Including the ones with awkward answers.

How does pay-as-you-go actually work?

You add credit, minimum $10. Sending draws it down. When a campaign starts, an estimate is held so it can't run out of money halfway through; when it finishes, the hold is released and you're charged for what was really sent. Credits don't expire and there's no monthly fee, so an account that sends nothing costs nothing.

Why is SMS billed per segment rather than per message?

Carriers bill that way. A plain message up to 160 characters is one segment. Go over, or include a character outside the GSM alphabet, such as a curly quote or an emoji, and the whole message re-encodes and can cost three times as much. Hiding that behind a flat per-message price would mean charging everyone for the worst case. The composer shows the segment count as you type.

What happens when a message fails?

A message the carrier accepts and then fails to deliver is refunded to your balance automatically when the failure notice arrives, usually within minutes. A message blocked before sending, because the recipient opted out, is never charged at all. You'll see both as line items.

Do I need a developer?

Not for sending. Import a CSV, write a message, send it. There's an API if you want to trigger messages from your own systems, which does need a developer.

Can I bring my own phone number?

Yes, and for regular sending you should. US carriers require business messaging traffic to be registered, and registration is tied to a number and a brand. We handle it with you. Expect days, not minutes. That's the carriers' timeline, not ours.

Is there a free tier?

No. Accounts are free to open and cost nothing while idle, but sending requires credit. Free anonymous SMS is how a sending reputation gets destroyed by people who aren't your customers, and the cost of that lands on everyone else sending through the same numbers.

What are you not good at yet?

Automation sequences, attribute-based segment building, and click reporting aren't finished. The platform was rebuilt recently and those screens are in progress. If one of them is what you need, say so and we'll tell you honestly whether to wait.
