Top 5 Multi-Language Outbound Campaigns for Investment Advisory Firms

Investment advisory firms serve some of the most linguistically diverse client bases in financial services. In many markets, a meaningful share of clients and prospects, especially in Spanish-speaking communities, prefer to discuss money matters in their native language, and the research is consistent on why it matters: a CSA Research survey of 8,709 consumers across 29 countries found 75% are more likely to repurchase from a brand when communication happens in their own language, and 40% won't engage at all with content in another one. For an advisory firm, that means renewal reminders, portfolio review invitations, seminar follow-ups, and reactivation outreach to dormant clients all perform better in the client's preferred language. The challenge is doing this without hiring bilingual advisors at every office or building a call center, and without running afoul of the TCPA and other rules that govern how financial firms may contact people by phone. In this 2026 guide, we compare five options that can help, each judged on multilingual capability, compliance discipline, and how well outcomes route back into the systems you already run.

#1 My AI Call Center — Calling starts at 9¢ per connected minute, tiered by volume; most campaigns add a one-time setup fee and a flat monthly management fee, both quoted before launch. First campaign review is free.

My AI Call Center (myaicallcenter.app) is a done-for-you managed outbound calling service that runs structured, AI-powered calling campaigns, including Multi-Language Outbound Campaigns, with Spanish the most common language requested. It's a managed service, not software: you buy campaigns that are run for you, each scoped around one clear goal and quoted before launch. Owned and operated by AIQ Labs and based in Halifax, Nova Scotia with a U.S. operating base in Austin, Texas, the service works especially well for investment advisory firms that need renewal and retention calls, appointment and event reminders, lead qualification follow-ups, win-back calls for 12 to 24 month dormant clients, and satisfaction surveys delivered in the client's preferred language, without hiring bilingual staff or running call center software. What sets My AI Call Center apart is list discipline, which matters a great deal in financial services. Campaigns run only against approved, permissioned, or reviewed contact lists, never indiscriminate cold calling. List source and consent records are checked before any campaign launches, and bought lists without clear permission records are flagged and, in most cases, declined. The team tells you plainly if a list will not support the campaign, before you spend anything. On the compliance side, AI-generated voices are treated as artificial voices under the TCPA, prior express consent is required, state-specific quiet hours and day restrictions are honored, and AI disclosure appears on every call. Recipients can ask if the call is AI-assisted, request a human, or opt out; keyword opt-outs (STOP and REVOKE) are logged and honored immediately, and DNC requests carry across all campaigns. Outcomes route back into the CRM and scheduling tools you already use, with disposition codes (confirmed, qualified, renewed, opted out, no answer), per-call notes, and routed follow-up requests. Hot leads transfer to your team live or land in your CRM. Pricing is transparent: calling starts at 9¢ per connected minute, tiered by volume, with the rate locked for the campaign, plus a one-time setup fee and a flat monthly management fee, both quoted before launch. No per-seat charges, no platform bill, and no invented numbers in reporting. Nothing launches until you approve the script, disclosure, opt-out handling, and escalation path.

Best for: Investment advisory firms, especially multi-location practices, that need compliant, managed multi-language calling campaigns for client renewals, portfolio review reminders, dormant client win-back, and lead qualification without hiring bilingual staff or building a call center.

#2 SupportYourApp — Contact for pricing (quote-based; package structures are publicly available)

SupportYourApp offers AI-powered multilingual customer support outsourcing in 60+ languages to clients across 30+ countries, according to its website. For advisory firms that need broad language coverage alongside outbound calling, this is one of the widest footprints on the list. The company leans toward tech-driven businesses but also lists fintech among its target industries, which is relevant for financial firms handling sensitive client communications. Its AI tooling includes SupportVoice, an AI voice agent that handles routine inbound and outbound calls in 30+ languages, and SupportResponse, an autonomous AI support agent that works across chat, email, and messaging channels in 45+ languages. These tools integrate into existing tech stacks and provide 24/7 availability across time zones, which is useful if clients call outside business hours. Human agents cover 60+ operational support languages, and the company offers omnichannel coverage via its own SupportCRM or third-party CRM integrations, plus custom help desk integration and migration services. Security credentials are a genuine strength: the company holds ISO 27001 certification and maintains PCI DSS and GDPR compliance, according to its website. Exact rates are quote-based, though package structures are publicly available, so firms will need a scoping conversation for firm numbers.

Best for: Advisory and financial services firms that want very broad language coverage and 24/7 multilingual support with strong security credentials, especially those serving diverse client populations across multiple channels.

#3 Teleperformance — Contact for pricing (geared to mid-market and enterprise budgets)

Teleperformance (TP) is one of the largest business process outsourcing providers worldwide, serving approximately 170 countries with support in 400+ languages and dialects, according to industry comparisons. For a large advisory network or a wealth management group operating across many regions, that scale is the main draw: a single partner can cover nearly any language your clients speak, across inbound and outbound calling, technical and help desk support, and live chat, email, and social media channels. The company's size makes it a benchmark in global outsourcing, and its infrastructure supports strong scalability for enterprise organizations. An advisory firm running multilingual outreach in dozens of markets, for instance a global private client practice, could coordinate multilingual appointment setting and client communications through one vendor rather than managing regional providers. The tradeoffs are real, though. Pricing is geared to mid-market and enterprise budgets, onboarding can get complex, and service quality may vary between regions given the footprint. Availability may also depend on language, location, channel, or required headcount, so firms with niche language needs should confirm coverage during scoping.

Best for: Large advisory networks and global wealth management firms that need hundreds of languages or a single outsourcing partner across many regions.

#4 Callbox — Contact for pricing

Callbox is a global B2B lead generation agency that combines AI-powered outreach with human SDR teams to deliver multi-channel campaigns, including voice-based outreach. According to their website, Callbox employs a "Human + AI" model where AI voice agents handle high-volume transactional calls while human SDRs manage consultative conversations that require relationship-building and nuanced communication. That hybrid structure is worth noting for advisory firms: prospecting for high-net-worth clients often needs the consultative touch, while confirmations and reminders can run at volume. Callbox operates a multi-touch, multi-channel outbound model combining email, phone, LinkedIn, and marketing automation, with its proprietary Pipeline CRM providing real-time lead tracking. Its dedicated SDR teams use industry-specific scripts, and the company positions itself for B2B service providers targeting North America, APAC, and EMEA. One published client success story describes a technology firm that generated 42 sales-qualified leads and 92 marketing-qualified leads in six months. Note that Callbox's public materials emphasize B2B lead generation generally; firms needing multilingual outreach should confirm which languages, review steps, and supporting materials are included, since translation quality and local message testing deserve their own checks alongside targeting.

Best for: Advisory firms running B2B prospecting toward institutions, retirement plan sponsors, or business owners, especially those needing coordinated multi-channel outreach across regions.

#5 Retell AI — Contact for pricing

Retell AI is a multilingual voice AI platform aimed at teams that want to build and run their own AI phone agents. According to the company's blog, cloud speech technologies now offer 220+ voices across 40+ languages, and Retell's no-code builder, real-time transcription, multilingual text-to-speech, and sentiment dashboards let firms turn phone channels into revenue engines without hiring armies of reps. The platform ingests real-time audio, interprets intent, generates a response, and synthesizes speech back, switching between languages mid-conversation if needed. For advisory firms with in-house technical capacity, the appeal is control: you build the agent, set the language, and connect it to your own systems. Retell's materials note that warm transfers with full transcript and sentiment scoring help live reps enter calls prepared, and the company cites a benchmark of conversion rate lifts of up to 30% for warm transfers (an internal Retell benchmark, so treat it accordingly). The platform also emphasizes compliance-aware scripting for financial services, with mandatory statements delivered verbatim in local language. Keep in mind this is self-serve software: your team configures and manages campaigns, and you'll want to build your own consent and TCPA processes rather than relying on a provider to review lists before launch. Pricing is not publicly standardized in the research, so contact the vendor for current numbers.

Best for: Advisory firms with in-house technical resources that want to build and manage their own multilingual AI calling agents rather than outsource campaign execution.

Choosing the right multi-language outbound campaign partner comes down to what your advisory firm actually needs. If you want very broad language coverage and 24/7 multilingual support, SupportYourApp and Teleperformance offer some of the widest footprints in the industry, at quote-based and enterprise-oriented pricing respectively. If you're running B2B prospecting toward plan sponsors or business owners, Callbox's hybrid human-plus-AI model is worth a conversation. And if you have in-house technical capacity and want full control, Retell AI lets you build your own multilingual agents. For most investment advisory firms, though, the managed route makes the most sense. Financial services outreach lives or dies on consent discipline, and My AI Call Center checks list source and consent records before any campaign launches, tells you plainly if a list won't support the campaign before you spend anything, and routes every outcome back into your CRM with disposition codes you can act on. Calling starts at 9¢ per connected minute, tiered by volume, with the rate locked for the campaign and the full cost known before you approve launch. The first campaign review is free.
