Brevo SMS Marketing Guide (2026): Setup, Costs & Campaigns That Work

Email gets ignored; SMS gets read. Text messages boast open rates that email marketers can only dream of — the vast majority read within minutes. That’s why Brevo bakes SMS into the same platform as your email, CRM, and WhatsApp: one contact record, one automation builder, multiple channels. This Brevo SMS marketing guide covers setup, real costs, compliance rules, and five campaign playbooks that actually work.

This guide covers everything: setting up SMS in Brevo, how the credit pricing works, the compliance rules you must follow, and the campaign playbooks that actually drive revenue. For the platform overview, see our Brevo review.

Brevo SMS marketing: Why Add SMS to Your Brevo Marketing

• Speed: time-sensitive messages (flash sales, appointment reminders, cart nudges) land instantly and get read instantly.
• Reach the unengaged: subscribers who ignore your emails often still read texts — SMS recaptures attention email lost.
• One platform: because Brevo unifies SMS with email and CRM, you can build workflows like “email first, SMS follow-up for non-openers” without duct-taping tools together.
• High intent moments: order updates, booking confirmations, and back-in-stock alerts feel helpful by text in a way they never do by email.

The flip side: SMS is intimate and interruptive. Abuse it and people opt out (or worse, report you). Every SMS you send should earn its interruption — which is exactly what the playbooks below are designed to do.

Setting Up Brevo SMS Marketing

Step 1: Enable the SMS channel

SMS is available within your Brevo account — there’s no separate product to buy. You’ll work with credits: each text message consumes credits based on its length and destination country.

Step 2: Purchase credits

Unlike your email allowance (which is part of your plan), SMS credits are bought separately in bundles. Credit costs vary by destination country — sending within your home country is cheapest; international sends cost more credits per message. Start with a small bundle while you test; you can top up as campaigns prove themselves.

Step 3: Set your sender identity

Choose how your texts appear — typically your brand name (alphanumeric sender ID) where carriers support it, or a local number. Branded sender IDs build recognition; check what’s supported in your recipients’ countries, as rules vary.

Step 4: Build your SMS list — with consent

You need explicit opt-in for SMS — email consent does not cover texting. Add an SMS opt-in checkbox to your Brevo signup forms (kept separate from email consent), run a keyword campaign (“Text JOIN to 12345”), or ask at checkout. Never import phone numbers into SMS sends without permission; the legal and reputational risk isn’t worth it.

Brevo SMS Marketing Costs: What You Actually Pay

Brevo doesn’t fold SMS into plan pricing — it’s pay-as-you-go via credits, on every plan including Enterprise. What drives your cost:

• Destination country: domestic texts cost the fewest credits; international rates are higher.
• Message length: a standard SMS is 160 characters (fewer with special characters/emoji, which force multi-part encoding). Two-part messages cost double — keep texts tight.
• Volume: credit bundles get cheaper per-credit at higher volumes.

Budgeting rule of thumb: price your highest-value use cases first (cart recovery, appointment reminders) where one converted message pays for hundreds of sends, then expand to promotional blasts once the math proves out. Because credits are separate from your email plan, SMS spending never threatens your email allowance.

Compliance: The Rules You Can’t Ignore

SMS is regulated more strictly than email in most countries. The non-negotiables:

• Express consent first. Every recipient must have opted in to SMS specifically. Keep records of when and how.
• Identify yourself. Every message should make clear who it’s from.
• Honor opt-outs immediately. Include opt-out instructions (“Reply STOP to end”) and process them automatically — Brevo handles STOP keywords for you.
• Respect quiet hours. Don’t text at 2am. Many jurisdictions restrict marketing texts to daytime hours; even where they don’t, midnight texts get you blocked.
• Transactional vs marketing. Order updates and security alerts have more leeway than promotions, but consent still matters — know which category each message falls into in your region.

When in doubt, be conservative. One spam complaint does more damage than ten cautious campaigns. Brevo SMS marketing works best as a complement to email, not a replacement — reserve texts for moments where minutes matter.

5 SMS Campaign Playbooks That Work

1. Abandoned cart SMS (the highest ROI text you’ll send)

Trigger: cart abandoned, no purchase after 1–3 hours, customer hasn’t opened your cart email. Message: “Hi [Name], you left [Product] in your cart at [Brand]. Still want it? [link]” — short, personal, one link. This single automation routinely outperforms entire email blasts. Pair it with your email cart flow (see our ecommerce guide) and suppress anyone who already converted.

2. Flash sale / limited offer

“[Brand]: 24 hours only — 25% off everything with code FLASH25. Shop: [link]. Reply STOP to opt out.” Works because SMS urgency is real — people act within minutes. Use sparingly (a few times a month max) or the channel burns out.

3. Appointment & booking reminders

“Reminder: your appointment with [Brand] is tomorrow at 2pm. Reply YES to confirm or call us to reschedule.” Cuts no-shows dramatically. Pure service value — the kind of text people thank you for.

4. Back-in-stock / price-drop alerts

Let shoppers subscribe to alerts for specific products, then text the moment it’s available. Intent couldn’t be higher — these convert at exceptional rates.

5. Post-purchase follow-up

“Your order shipped! Track it here: [link]. Questions? Just reply.” Then a week later: “How’s your [Product]? Tap to leave a review: [link]” — review collection via SMS dramatically lifts response rates versus email.

Combining SMS With Email in Brevo Automations

The real power move is orchestration. In Brevo’s workflow builder (Standard plan and up — see our automation guide): Mastering brevo sms marketing is less about tools and more about consistency — the fundamentals above cover 90% of what matters.

• Email first, SMS as backup: send the promotion by email; 24 hours later, text only the non-openers with a shorter version. You reach everyone without doubling costs.
• SMS for the urgent, email for the detailed: text “sale ends in 3 hours” with a link; let the email carry the full lookbook.
• CRM-triggered texts: when a deal moves to “negotiation” in Brevo’s free CRM, auto-text the rep to follow up — internal SMS is underused and effective.

Mistakes That Kill SMS Programs

• Texting too often. 2–4 promotional texts a month is plenty for most businesses. Daily texts = mass opt-outs.
• No opt-out path. Illegal in many places, infuriating everywhere.
• Walls of text. Multi-part messages cost double and read terribly. One idea, one link, under 160 characters.
• Sending email content by SMS. “Our October newsletter is here!” is not a text message. Rewrite for the channel.
• Ignoring replies. If people can reply, someone must read the replies — or disable two-way messaging and say so.

SMS vs Email in Brevo: When to Use Which

Having both channels in one platform raises the strategic question: which message goes where? A simple framework:

• SMS when: it’s time-sensitive (sale ends tonight, appointment tomorrow), high-intent (cart abandoned, back in stock), or service-critical (order shipped, security alert). The rule: if waiting a day would meaningfully change the outcome, text it.
• Email when: it’s content-rich (newsletter, lookbook, tutorial), low-urgency (monthly update, brand story), or needs formatting (tables, multiple images, long copy).
• Both, sequenced: launch announcements (email with full details → SMS reminder on final day to non-openers), event invites (email invitation → SMS reminder morning-of), cart recovery (email at 2 hours → SMS at 24 hours for non-openers).
• WhatsApp when: your audience genuinely prefers it — strong in much of Europe, Latin America, and Asia; less so in the US. Match the channel to the customer, not your preference.

The cost logic reinforces this: email is effectively prepaid in your plan allowance, while each SMS costs credits. Spend texts where speed and attention are worth paying for; let email carry everything else.

Measuring SMS ROI

SMS performance is easier to attribute than email because the action window is so tight. Track: The compliance rules around Brevo SMS marketing are strict for a reason; one violation can end your program.

• Delivery rate: should be very high — failed SMS deliveries usually mean bad numbers, so clean aggressively.
• Click-through rate: use tracked short links (your own domain, not generic shorteners) to measure precisely.
• Conversion rate and revenue per send: the only metrics that justify the credit spend. A cart-recovery SMS converting at 5%+ pays for itself hundreds of times over.
• Opt-out rate per campaign: your early-warning system. A spike means the message, frequency, or targeting was wrong — diagnose before the next send.
• Cost per conversion: total credit cost divided by conversions. Compare against your email cost per conversion to allocate budget between channels rationally.

Run your first month as an experiment: pick one high-intent use case (cart recovery is the classic), measure cost per conversion against email-only, and expand only when the numbers justify it. Most businesses find 1–2 SMS use cases that print money and leave the rest to email — that’s the correct outcome, not a failure. Track Brevo SMS marketing ROI separately from email; the open rates will flatter you, but revenue per message is the honest metric.

Our Verdict

Brevo’s SMS offering stands out because it’s not a bolt-on — it shares your contacts, segments, automations, and CRM with everything else, and the pay-as-you-go credit model means you only spend when you send. The costs are transparent, the compliance tooling (STOP handling, consent tracking) is built in, and the email+SMS orchestration is genuinely best-in-class at this price. Just remember: SMS is a privilege, not a channel — earn every send. It’s another reason Brevo holds 4.5/5 in our review. Done right, Brevo SMS marketing earns its place alongside email — start with one playbook and measure everything.
