Best Multi-Language Outbound Campaigns for New Construction Sales Teams

New construction sales teams sell into some of the most linguistically diverse markets in North America. Whether you're following up on model home visits, qualifying lot inquiries, confirming design appointments, or reactivating prospects who went quiet six months ago, English-only outreach quietly loses a share of every market. The U.S. Census Bureau counts 25.7 million people living with limited English proficiency, and a CSA Research survey of 8,709 consumers across 29 countries found 75% are more likely to engage with a brand that contacts them in their native language. For a builder or developer, that gap shows up as missed appointments, unreturned quote follow-ups, and prospects who buy from a competitor that simply called them in Spanish. The practical problem is staffing: you can't hire bilingual salespeople for every language in every market, and traditional call centers charge per seat with long contracts. This 2026 guide compares five providers that genuinely support multi-language outbound campaigns, evaluated on language coverage, compliance posture, pricing transparency, and how well outcomes route back into the CRM and scheduling tools a construction sales team already runs.

#1 My AI Call Center — Calling starts at 9¢ per connected minute, tiered by volume; most campaigns add a one-time setup fee and 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 commonly requested language. It is a managed service, not software: you buy campaigns that the team runs for you, each scoped around one clear goal and quoted in full 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 is built for multi-location organizations of 1 to 200+ staff, including property and customer services businesses like new construction sales teams that need lead qualification, speed-to-lead follow-up, appointment reminders, win-back calls, and database reactivation delivered in the language prospects actually speak, without hiring bilingual staff or running call center software. What sets My AI Call Center apart is list discipline. 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. For a builder calling people who visited a model home or submitted an inquiry form, that matters: AI-generated voices are treated as artificial voices under the TCPA with prior express consent required, AI disclosure appears on every call, recipients can ask if the call is AI-assisted, request a human, or opt out, and STOP and REVOKE keyword opt-outs are logged and honored immediately. State-specific quiet hours and day restrictions are respected, and DNC requests carry across all campaigns. Outcomes route back into the CRM and scheduling tools you already run, 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. Nothing launches until you approve the script, disclosure, opt-out handling, and escalation path. Pricing is transparent: calling starts at 9 cents 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.

Best for: New construction sales teams and multi-location property businesses that need compliant, managed multi-language calling campaigns for lead qualification, appointment reminders, quote follow-ups, and win-back outreach without hiring bilingual staff or building a call center.

#2 Martal Group — Approximately $4,100 to $7,000 per month minimum with a 3-month pilot, per third-party review data; exact rates require a consultation.

Martal Group is an outsourced B2B sales agency founded in 2009, running outbound lead generation across email, LinkedIn, cold calling, and SMS with 200+ onshore sales executives across North America, EMEA, and LATAM. According to their published materials, the company supports multi-language capability in English, Spanish, German, and French, which enables genuine execution in Spanish-speaking markets rather than English-only campaigns sent to international targets. Their model centers on intent-data timing, using Bombora-powered intent data covering 18,000+ topics to reach buyers when they are already in the market. For new construction sales teams selling commercial projects, multi-family developments, or B2B building products, Martal's outbound lead generation tier targets 3,000 to 5,000 prospects monthly with 250 to 450 calls initiated, aiming for 20 to 30 qualified leads per month. Their senior-rep positioning means conversations are handled by mid-to-senior-level sales professionals rather than junior SDRs. The engagement structure runs as a 3-month pilot before moving to monthly terms, and published case studies include clients such as Bosch, HALO Recognition, and Jedox.

Best for: Commercial construction and building products companies selling B2B that need multi-language outbound across English and Spanish markets with intent-driven timing.

#3 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 construction sales teams needing broad language coverage alongside outbound calling, it has one of the widest footprints on the list. 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 working across chat, email, and messaging channels in 45+ languages. Human agents cover 60+ operational support languages, with omnichannel coverage via its own SupportCRM or third-party CRM integrations. Security credentials are a genuine strength: SupportYourApp holds ISO 27001 certification along with PCI DSS, GDPR, and HIPAA compliance. The company also builds custom AI solutions designed to match a brand's tone. A published example illustrates the approach: for Flibco, an airport shuttle service expanding into new markets with irregular request volumes, SupportYourApp built a scalable 24/7 English and French team that improved response times and CSAT scores. Exact rates are quote-based, though package structures and included features are publicly available.

Best for: Construction and property companies expanding into multiple international or multilingual markets that need broad language coverage across voice and digital channels with strong security credentials.

#4 Callbox — Contact for pricing.

Callbox is a global B2B lead generation and appointment setting agency that runs multi-touch, multi-channel outbound campaigns combining phone, email, LinkedIn, and marketing automation. 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. This hybrid approach supports scalable outbound efforts in multiple languages, particularly through AI-powered voice capabilities that initiate contact before transitioning to human agents for qualified conversations. For new construction sales teams selling commercial projects, multi-family developments, or building services into corporate accounts, Callbox's multi-channel strategy can support booking follow-ups, appointment setting, and customer surveys. The company emphasizes precision targeting using Ideal Customer Profile definitions and AI-enriched data, and it operates with localized campaign execution across APAC, EMEA, LATAM, and North America, with operations in over 60 countries. Their proprietary Pipeline CRM provides real-time lead tracking, and dedicated SDR teams work from industry-specific scripts. A published case study describes a technology client that generated 42 sales-qualified leads and 92 marketing-qualified leads over six months.

Best for: Construction companies with commercial or multi-market reach that need scalable, human-AI hybrid multilingual outreach across multiple channels and regions.

#5 Teleperformance — Contact for pricing.

Teleperformance (TP) is one of the largest BPO providers worldwide, serving approximately 170 countries with support in 400+ languages and dialects, according to published company information. Its scale makes it a benchmark in global outsourcing, and for construction enterprises with international operations, that language ceiling is essentially unlimited. Key services include inbound and outbound call center services, technical and help desk support, and live chat, email, and social media support. For a large construction or property development organization running outbound campaigns across many markets at once, Teleperformance offers the staffing depth to run parallel campaigns in multiple languages simultaneously. The trade-offs are structural: pricing is geared to mid-market and enterprise budgets, onboarding can be complex given the organizational footprint, and service quality may vary between regions. Availability may also depend on language, location, channel, or required headcount. It is the right fit when language breadth and enterprise scale matter more than speed to launch or per-campaign pricing transparency.

Best for: Large construction enterprises and multinationals that need hundreds of languages or a single outsourcing partner across many regions at once.

The right multi-language outbound partner for a new construction sales team depends on what you're selling and who you're calling. If your list is made up of model home visitors, lot inquiries, and past prospects, a managed, consent-checked calling service like My AI Call Center gives you structured campaigns in your prospects' preferred language with TCPA-aligned compliance, locked pricing from 9 cents per connected minute, and outcomes routed straight into your CRM. If you're selling commercial projects into B2B accounts, Martal Group and Callbox offer multi-language outbound with human sales execution across regions. If you need the widest possible language coverage, SupportYourApp and Teleperformance cover dozens to hundreds of languages. Whichever direction you take, check the list discipline first: a campaign is only as compliant as the list and consent records behind it. Start with a free campaign review at myaicallcenter.app, where the team will scope one clear goal, quote the full campaign before launch, and tell you plainly if your list won't support the campaign before you spend anything.
