Best text message archiving software for financial firms

Your advisers already text clients from phones and numbers the firm did not pick. Text message archiving software copies those texts at the carrier or on the phone and keeps them as records. We read seven SMS archiving tools against the adviser and broker-dealer rules, from each vendor's own pages, including where those pages are silent.

Reviewed October 2026

Best overall

Smarsh

Captures texts from carriers it names, AT&T, Verizon and T-Mobile among them, on firm and BYOD phones, into an archive whose own pages state WORM storage, undertaking letters and named export formats.

Best for a firm that already has an archive

CellTrust

A capture layer only: carrier, app and stacked capture deliver texts to the archive the firm already runs, with native Microsoft Purview integration, so nothing is bought twice.

Three places a text can be captured

Text message archiving software does two jobs: it copies each text as it is sent and received, and it keeps that copy where it cannot be lost or changed. The first job decides whether you get every text at all, so start there. A text can be copied in one of three places, and each one sees a different slice of what advisers send.

Where the copy is made

Three capture points for text messages compared
Capture pointHow it worksWhat the adviser changesWhat it missesIn this table
At the carrierThe carrier copies each SMS and MMS on the line and sends it on to be archivedNothing: same phone, same number, same texting appiMessage and WhatsApp; lines on carriers the vendor does not supportSmarsh, CellTrust, Jatheon, Intradyn
On the phoneA profile, app or connector on the device reads the phone's own messaging appsEnrols the phone once and keeps the number; picks business contacts if there is a whitelistPhones that were never enrolledArchive Intel, MirrorWeb, Jatheon, Intradyn, Global Relay (Android)
On a second numberA business number the firm owns runs in an app beside the personal lineClients must text the new numberTexts clients still send to the adviser's own numberCellTrust App Capture; the texting apps on our texting page

The second number is the design most compliant texting apps for advisers use, and those apps are compared on their own page. This page reads the other two: capture that leaves the adviser's phone, number and habits as they are, and the archive the copies end up in.

Blue bubbles, green bubbles: what a carrier sees

An iPhone sends three kinds of message from the same Messages app, and a carrier feed does not see all of them. Apple's own support page sets out the difference.

The carrier capture pages we read name SMS and MMS; none of them names iMessage. So a carrier feed on an adviser's iPhone keeps the green bubbles and misses a client conversation that runs in blue. If your advisers and clients are mostly on iPhones, the iMessage column matters more than the carrier column: capture on the phone, or a written policy that keeps business off iMessage, and someone who checks. WhatsApp is the same case, and both apps are read vendor by vendor in our WhatsApp and iMessage archiving comparison.

RCS is the open question for the next year. CellTrust names RCS capture, Global Relay captures RCS from the default Android app, and Intradyn lists RCS among its channels. Ask any vendor in writing whether it captures RCS on your carriers today, and what changes once your carrier encrypts RCS end to end.

Firm phones, personal phones and the method that fits

The phone decides the method. CellTrust's carrier page describes the firm-issued, business-only phone (it calls it COBO, “Corporate Owned Business Only”) as the setup where carrier capture fits, because everything on that line is business. A personal phone is the opposite case: the firm must keep the business texts and should leave the rest alone, which is what the whitelists at Archive Intel, Jatheon and MirrorWeb, and CellTrust's separate business number, are for.

A firm-paid line, business only
Carrier capture, if the vendor supports your carrier. CellTrust names AT&T and Verizon in North America; Smarsh and Jatheon each name more.
The adviser's own phone and own number
Capture on the phone with a business-contact whitelist. Ask what the enrolment can see on the device.
A mix of both
A vendor that offers more than one route: Jatheon, Intradyn and CellTrust (Stacked Capture puts carrier and app capture on one device).

Answer four questions and the picker reads the table for you.

The method that fits

Capture on the phone

Personal phones need capture that keeps business texts and leaves personal ones out.

Listed: vendors whose own pages state each need in full (Meets) or in part (Partial), most Meets first.

The archive side: where the record ends up

Capture is half the job. The copy has to sit somewhere that keeps it for the full period, finds it on request and produces it readable. Six of the seven vendors here capture and archive in one product, and one of them, Smarsh, will also deliver to an archive you already run. CellTrust only captures and hands the texts to an archive you pick. Which shape suits you depends on what you already pay for: our email archiving comparison covers the archives most firms start with.

How long the texts are kept is set by the rule, not the vendor. An adviser keeps written communications on the subjects Rule 204-2(a)(7) lists, advice and recommendations among them; a broker-dealer keeps all communications relating to its business as such under Rule 17a-4(b)(4).

Investment adviser: not less than five years

Year 0: End of the fiscal year of the last entry

  • In an appropriate office of the adviser2 years
  • Easily accessible place, rest of the period3 years

17 CFR 275.204-2(e)(1)

Broker-dealer communications: not less than three years
  • Easily accessible place2 years
  • Rest of the period1 year

17 CFR 240.17a-4(b); FINRA Rule 3110.09

Rule 17a-4(b) states the length and the easily accessible window but not the event the three years run from, so set that start point with your compliance counsel. Our retention calculator works out the adviser date. A dual registrant can lean on Rule 204-2(h)(1), which deems a record kept under the broker-dealer rules, if it is substantially the same, to be kept under the adviser rule as well.

The form of storage differs too. A broker-dealer's system must keep a complete time-stamped audit trail or keep records in a non-rewriteable, non-erasable format, and must be able to download a record in a human readable and a reasonably usable electronic format. Where a vendor owns and operates the servers, it must file a written undertaking that the records are the firm's and will be surrendered promptly on request. An adviser's rule, 204-2(g), has no WORM requirement; it asks for an index, a duplicate copy, safeguards against loss, alteration or destruction, and prompt production. The detail is in our guides to Rule 17a-4 and WORM storage and Rule 204-2 books and records.

Reviewing texts once they are archived

A broker-dealer must review incoming and outgoing written (including electronic) correspondence under written procedures, and FINRA lets it decide by risk how much to review, provided it trains its people, documents the training and runs surveillance and follow-up (Rule 3110.06). Keyword flags are the surveillance. The record of the review is the part most text archives leave unsaid.

FINRA Rule 3110.07 says that evidence must identify the reviewer, the message, the date and the action taken, and that merely opening a message is not review. That is why the review column reads Meets only for Global Relay, whose page names proof-of-review reports; every other vendor here names flags or alerts but not the review record. An adviser has no FINRA review rule, but must adopt and implement written policies and procedures reasonably designed to prevent violation of the Advisers Act and its rules (Rule 206(4)-7(a)); check with your compliance counsel how those policies should cover client texts. Our guide to FINRA Rule 3110 supervision covers the procedures.

Auto-delete on the phone is not retention

Without capture, the firm's retention schedule for texts is whatever each phone is set to. Capture copies a text as it is sent and received, and Jatheon and MirrorWeb both say on their own pages that edited and deleted messages are kept; ask every vendor how its capture handles a message the adviser later edits or deletes. In April 2026 the SEC said the earlier off-channel cases rested on “a misinterpretation of the federal securities laws” (press release 2026-34), but the record rules quoted above did not change. Our guide to off-channel communications covers the cases, and the off-channel policy builder drafts the written policy.

What to ask before you sign

Each vendor card below ends with a Not verified by us line. These seven questions sit behind those lines; ask them in writing, because the answer becomes part of your record too.

Smarsh

Carrier capture and archive
What it is
Smarsh Mobile Capture & Archiving takes SMS, MMS, WhatsApp Business and iMessage (where supported) straight from carrier networks it names, AT&T, Verizon, T-Mobile and US Cellular among them, and from apps on corporate-owned and BYOD phones, with no step for the employee. Texts go to the Smarsh archive or to an archive, records system or data lake the firm already has. Its archive page states immutable WORM storage for SEC 17a-4 and exports in PST, EML, HTML and XML; its 17a-4 page says it provides letters of undertaking.
Who it fits
A broker-dealer or dual registrant whose advisers text on firm-paid lines with a major US carrier, and that wants capture, storage, review and export from one vendor.

CellTrust

Capture layer, no archive
What it is
A capture layer, not an archive. Its SL2 Enterprise platform captures texts four ways: Carrier Capture on corporate-liable phones, where the carrier copies SMS and MMS from the phone's own messaging app with no extra app (AT&T and Verizon in North America); App Capture, which puts a separate business number the firm owns on a personal phone; Stacked Capture, both on one device; and RCS Capture. Messages then go to the archive the firm chooses, with native Microsoft Purview integration.
Who it fits
A firm that already pays for an archive, or keeps its records in Microsoft 365, and needs advisers' texts added to it rather than a second archive to run.

Global Relay

Android capture and archive
What it is
Global Relay for Android Messages captures SMS, MMS and RCS from the default texting app (Google Messages or Samsung Messages) on corporate-issued Android phones, keeps the existing corporate numbers and works with the firm's existing carriers. Texts land in the Global Relay archive with automated audit trails, optional WORM-compliant storage, retention terms and legal holds, and supervision with AI and lexicon tools whose reports cover proof of review.
Who it fits
A firm that issues Android phones to its advisers and wants texts reviewed in the same archive as its email and chat.

Archive Intel

On-phone capture and archive
What it is
An archive and supervision platform for SEC- and FINRA-regulated firms that captures texts on the phone rather than at the carrier: iMessage, WhatsApp and Android texting in the native apps, on personal and firm phones. Its FAQ says personal-phone capture typically needs a lightweight mobile profile, and a contact whitelist keeps personal texts out. It states WORM-compliant cloud storage, an access audit trail, retention by channel and record type, and a formatted export without IT.
Who it fits
An RIA or broker-dealer whose advisers text clients from their own iPhones and want to keep their own number.

Intradyn

Email and text archive
What it is
An archive for email, social media and texts. Its text page offers a lightweight Android or BYOD app, carrier-level capture, iMessage, WhatsApp, or any combination, on company or personal phones, with SMS, MMS and RCS named. Its financial page names broker-dealers and investment advisors, custom retention policies and exports in native or PDF format, and says it supports tamper-proof retention under either 17a-4 storage mode. Scheduled searches flag terms the firm defines.
Who it fits
A small firm that wants email and texts searched in one plain archive and will settle the storage mode in writing before it signs.

Jatheon

Multi-route capture and archive
What it is
An archive, in the AWS cloud or on a hardware appliance or VM behind the firm's firewall, whose text page names three capture routes: app-based capture, enterprise numbers, and direct carrier integrations with AT&T, Verizon, Vodafone, O2, T-Mobile and TELUS for corporate-owned iOS and Android phones. It keeps SMS, MMS, iMessage, WhatsApp, WeChat, voicemail and call logs as threaded conversations, leaves personal contacts out with whitelists and blacklists, and alerts supervisors on keywords.

How we read these vendors

Questions firms ask

Can carrier capture archive iMessage?

Not on the pages we read. Apple says iMessage travels between Apple devices over Wi-Fi or cellular data and is encrypted end to end, while the carrier capture pages name SMS and MMS. To keep iMessage, firms use capture on the phone (Archive Intel, MirrorWeb, Jatheon and Intradyn name it) or a written policy that keeps business off it. The record rules do not name any app; they cover the message.

17 CFR 275.204-2(a)(7); 17 CFR 240.17a-4(b)(4)

Does an adviser's text archive have to be WORM?

No. Rule 204-2(g) lets an adviser keep records electronically if it indexes them, keeps a duplicate copy, safeguards them from loss, alteration or destruction and can produce them promptly. It has no WORM requirement.

A broker-dealer's system must keep either a complete time-stamped audit trail or a non-rewriteable, non-erasable copy.

17 CFR 275.204-2(g); 17 CFR 240.17a-4(f)(2)(i)(A)-(B)

Who files the undertaking when a vendor holds our texts?

For a broker-dealer, an outside service that owns and operates the servers must file a written undertaking with the SEC that the records are the firm's property and will be surrendered promptly on request. Ask the vendor whether it files one for your account; Smarsh's 17a-4 page says it provides letters of undertaking. The rule has no such step for an adviser.

17 CFR 240.17a-4(i)(1)

How long must archived texts be kept?

An adviser keeps them not less than five years from the end of the fiscal year of the last entry, the first two years in an appropriate office. A broker-dealer keeps communications not less than three years, the first two in an easily accessible place, and FINRA ties correspondence retention to that same period. Check with your compliance counsel before setting any shorter schedule.

17 CFR 275.204-2(e)(1); 17 CFR 240.17a-4(b); FINRA Rule 3110.09

Can personal texts stay out of the archive?

The rules ask for business records, and vendors offer two ways to leave the rest out: a business-contact whitelist on the adviser's own number (Archive Intel, Jatheon and MirrorWeb describe one), or a separate business number the firm owns (CellTrust App Capture). Carrier capture copies everything on the line, which is why it suits a firm-issued, business-only phone.

17 CFR 275.204-2(a)(7); 17 CFR 240.17a-4(b)(4)

Is any text archiving software FINRA approved?

No. Neither FINRA nor the SEC approves vendors, and FINRA retired its Compliance Vendor Directory effective March 19, 2024. A vendor's compliance claim describes its product; the recordkeeping and review duties stay with the firm.
