Best mobile marketing services and agencies compared, and the consent record that decides which supplier you can use

Eight phrasings arrive at one purchase, and the supplier market splits into four that do not compete. The sorting question is who holds the consent record, because it is the only thing in this category that is legally yours.

Published by AI Knows Us · Updated 22 October 2026

Mobile marketing services is a phrase covering four supplier types that almost never compete for the same brief, and the one question that sorts them is not about creative or channels. It is about who holds the consent record for the phone numbers and device identifiers in the campaign, because that asset is the only part of a mobile programme that stays yours when the supplier changes.

Ask it in the first call. The answer determines what you can do in year two.

The four suppliers behind one search

The messaging specialist. SMS, MMS and increasingly WhatsApp. Lives inside a sending platform, writes the sequences, manages the number, handles opt in capture and opt out. The deliverable is a list that grows and a revenue number per send. Judge it on deliverability and on how opt outs are honoured, not on copy.

The app marketing agency. Install campaigns, store optimisation, retention sequences, in app events. Measured on cost per install and then on day thirty retention, and the gap between those two metrics is where most app budgets are wasted. A messaging shop cannot do this work and will say it can.

The mobile media buyer. In app advertising inventory, programmatic, location targeted display, mobile video. Priced as a percentage of spend. This is a media business and the consent record it touches is somebody else's.

The mobile experience team. Responsive site work, mobile checkout, page weight, tap targets, progressive web apps. Engineering work sold as marketing, and the highest return of the four for most retailers because it fixes a leak rather than adding traffic.

Most briefs that say mobile marketing mean one of those four and get pitched all four.

The consent question, in the order to ask it

Where is the opt in stored. In the agency's platform account, or in yours. If it is theirs, your list is hostage to the relationship, and that is a commercial fact rather than bad faith.

What exactly did the subscriber agree to. The wording of the capture matters more than the volume captured. A consent for order updates does not cover promotional sends, and the record has to show which was given, when, and from what page.

Who owns the sending number or short code. A number carries reputation. Changing it resets deliverability and silently loses recipients.

How are opt outs synchronised. Across every system, immediately. One unsynced suppression list is how an organisation sends to someone who left twice and discovers it in a complaint.

What happens to the list on the day we leave. Get the export format and the notice period in writing at the start. Nobody negotiates this well at the end.

Two of those five are usually unanswered in a proposal. Put them in the brief rather than the contract, because the answers change who you shortlist.

The mobile surface nobody in this category is measuring

Every supplier above works on a screen the customer is already holding, which is the right description of mobile marketing for the last fifteen years. One thing has changed and none of the four has a product for it.

A customer on a phone now asks an assistant who to use, rather than opening a search results page and scrolling. The assistant replies in a sentence with two or three business names in it. There is no impression, no tap and no install to attribute, so nothing in a mobile marketing report has ever seen that moment, and it happens overwhelmingly on mobile because that is where assistants are used.

For the advertising platform side of the same shift, including the second AI surface that sells no advertising at all, this site carries best AI advertising platforms. Measured on 21 October 2026, no other page on this site links to that one, out of 2,405 live pages of which 982 have no inbound internal link by the same measure, 40.8 percent and an upper bound.

What AI Knows Us is on this page, and the two places it is the wrong purchase

AI Knows Us sends no messages, buys no in app inventory, writes no sequences and holds no consent record. We are not a mobile marketing agency and a buyer who put us on this shortlist would arrive wanting a supplier we are not.

What we are is a measurement of that one unattributed mobile moment. We ask a buyer's real question on ChatGPT, Gemini, Perplexity, Claude and Google AI Overviews, with the business name kept out of the question, and report which businesses get named. Read at aiknowsus.com/pricing on 23 October 2026, Growth is $299 a month for 100 buyer questions, 1,200 scheduled answers and all five apps, and a Claude check uses 3 credits "because Claude costs us more to run" while most checks use one. The published floor, SEO Start at $149, watches 0 buyer questions on 0 engines and buys none of this, so a sentence pairing $149 with five surfaces would be false.

Two cases where we are the wrong thing to buy, stated plainly. If your mobile programme is a messaging list and your problem is deliverability, this measurement will not help you and a messaging specialist will. And if you want to sample this surface before paying anything, BrightLocal publishes a free one-off checker: read on 21 October 2026, it gives "Check up to 5 prompts" against one location on your choice of "Google AI Mode, or ChatGPT", delivered as a PDF to an email address with no card. We publish no free check, so for a first look that beats us.

Questions buyers ask about mobile marketing suppliers

Can one agency do all four? A few genuinely can, usually at the larger end, and the test is whether they will name the person doing each part. A single blended rate across all four hides which one is being subcontracted.

Is SMS still worth it with open rates that high? The open rate is not the question. The consent base is. A small, properly captured list outperforms a large, loosely captured one and carries far less risk.

Who should own mobile site performance? Whoever owns the site. Buying it from a marketing agency works only when that agency has engineering capacity in house, and most do not.

Do we need a separate supplier for the assistant surface? Today yes, because none of the four measures it. Whether that remains true depends on vendor roadmaps and nobody has published a date.
