WhatsApp template preview, and the tools inside Ultra WhatsApp

Number validator & formatter

Checks pasted numbers and converts them to international E.164 format.

• Invalid or incomplete numbers
• Landlines and other non-mobile numbers
• Duplicates, even when written differently
• Numbers on your opt-out list

List cleaner

Finds the contacts in a list that should not get the next campaign, and removes the groups you tick from that list.

• On the opt-out list, or no opt-in recorded
• Landlines and numbers that are no longer valid
• Failed before as undeliverable (131026) or stopped marketing messages (131050)
• Sent three or more times and never delivered

Contacts stay in All contacts; only the list changes.

Template variable previewer

Fills a template's variables from a contact's fields or fixed text and shows the exact chat bubble a customer gets.

• Header, body, footer and buttons as they will appear
• Values from any contact field, with fallbacks
• Whether every variable is filled
• The API data Ultra WhatsApp would send

Message compliance checker

Reviews a template's text before you submit it to Meta, and scores how likely a rejection is.

• Lengths against Meta's limits (body 1,024 characters, header and footer 60, button text 25)
• Variables in order, not side by side, and not at the very start or end of the body
• An opt-out line or Stop button on marketing templates
• Link shorteners, spam-like phrases and too many exclamation marks

A checklist, not legal advice. Meta's own review decides.

Cost estimator

Estimates what Meta will charge for a list or a number of messages.

• Opted-in contacts grouped by country
• Template category (marketing, utility, authentication)
• At the per-message rates in an editable table you update from Meta's rate card

Always an estimate; Meta's invoice is what counts.

Quality & messaging limits

Shows each number's quality rating, messaging-limit tier and use in the last 24 hours.

• How the tiers grow
• What each quality rating means
• Tips that keep quality high

Quick single send

Sends one template to one number, or a text or media reply inside an open 24-hour window.

• Template preview before sending
• The 24-hour rule enforced for free text and media

Error code reference

Every common WhatsApp API error explained in plain language, with what to do.

• Search by code or words
• Which errors are retried automatically

Click-to-send (no API)

Walks a small opted-in list one person at a time and opens each chat with the message filled in. You tap Send yourself in WhatsApp.

• Leaves out opted-out, duplicate and invalid numbers, and people with no opt-in when it is required
• Up to 200 people in a session
• Warns you from 40 confirmed sends a day, and when you move faster than a sensible gap between chats
• Mark each person as sent, skipped or opted out

Nothing is sent for you, and no delivery reports come back. Above about 50 a day, use the official API: WhatsApp restricts numbers used for bulk sending.
