Maropost vs. Mailchimp:
Best SMS Marketing Software for Growing Businesses
This comparison reviews Maropost and Mailchimp SMS marketing software for growing business SMS programs. Compare text message marketing, SMS marketing automation, MMS, compliance, list growth, two-way SMS, and reporting side by side.
SMS Marketing Software & Text Message Campaign Features
Maropost lets you broadcast promotional SMS, including sales, launches, and reminders, to lists of opted-in subscribers. This is Maropost's core bulk SMS use case for marketing, distinct from one-to-one transactional alerts.
Mailchimp lets marketers with the SMS Marketing add-on create and send text campaigns to subscribed SMS contacts in supported sending countries after program approval.
Maropost supports MMS (Multimedia Messaging Service) so you can send images and GIFs with your texts, ideal for retail brands showing products visually. Available in US, Canada, and Australia.
Mailchimp supports MMS in the US and Canada on Standard plans and higher, attaching one JPEG, PNG, or GIF up to about 600 KB that automatically converts the send to MMS.
Maropost simplifies SMS campaign creation in two steps: (1) compose your message and compliance details, (2) choose your audience, schedule, and send. The workflow is built for non-technical marketers.
Mailchimp walks marketers through SMS creation in the SMS builder with audience selection, content editing, link settings, scheduling, and compliance checks before send.
Maropost includes a live preview panel that shows how your SMS or MMS will render on a mobile device as you type, helping you catch formatting issues before sending.
Mailchimp previews SMS and MMS content in the builder, including character and message counts, and supports sending a preview text to test copy before launch.
Maropost lets you insert contact tag merge fields into SMS content to personalize each message with profile data such as names, preferences, custom attributes, and more.
Mailchimp personalizes SMS with merge tags and audience data so marketers can insert contact fields and dynamic content into marketing text messages.
Maropost lets you embed mobile keywords in campaign copy so recipients can text back a specific word (e.g. SALE, STOCK) to trigger automatic actions like list subscribe or coupon delivery.
Mailchimp collects SMS consent through signup forms and compliant opt-in flows, rather than embedding custom mobile keywords inside every promotional broadcast body.
Maropost gives you flexible send options: schedule SMS for a future date and time, send immediately with Send Now, or save campaigns as drafts to finish later.
Mailchimp lets teams send SMS campaigns immediately or schedule them for a future date and time once the SMS program is approved and credits are available.
Maropost schedules campaigns relative to each recipient's timezone when permitted sending hours use contact-local timezone mode, so messages arrive at appropriate local times.
Mailchimp applies program-level sending rules and rate limits configured during SMS registration, with merchants responsible for respecting local quiet-hour expectations.
Maropost's Compliance tab lets you control the order and visibility of required elements such as organization name, message body, company link, and opt-out instructions in the final text.
Mailchimp includes required opt-out instructions in the SMS builder and enforces compliant consent collection during the SMS Marketing application process.
Maropost supports transactional SMS for automated, event-triggered messages like order confirmations, password resets, and OTP codes. Create templates in the UI and trigger sends programmatically via REST API when events occur.
Mailchimp focuses on marketing SMS through the SMS builder and Marketing API, rather than a dedicated transactional SMS REST deliver campaign editor for OTP sends.
SMS Compliance, 10DLC & Deliverability
Maropost helps teams meet US commercial SMS requirements with verified toll-free numbers or approved 10DLC. Unverified toll-free numbers have strict daily/weekly/monthly send limits. Maropost recommends toll-free over 10DLC for cost and approval speed.
Mailchimp guides merchants through an SMS Marketing application with business, sender, use-case, privacy, and carrier registration sections before approving a sending number.
Maropost lets you configure the legal window when SMS can be sent (default 9 AM to 6 PM) using campaign timezone or each contact's local timezone. Journey SMS auto-pauses outside this window.
Mailchimp documents permitted sending practices and displays informational rate limits in SMS settings, with merchants scheduling sends to avoid restricted local windows.
Maropost lets you set default organization name and company information link at the account level. These values auto-populate every new SMS campaign's Compliance tab.
Mailchimp centralizes SMS program settings including sender information, credits, compliance details, and rate limits on the SMS Overview and settings pages.
Maropost supports compliant opt-in collection, but regulations require you to document how and when each contact opted in: timestamp, method, IP address, phone number, and identity. You must retain these records.
Mailchimp requires explicit documented SMS consent before contacts receive marketing texts, with consent records captured through signup forms and opt-in workflows.
Maropost sends from a shared short code by default. You can request a dedicated 5–6 digit short code exclusive to your brand so recipients always see the same sender. Available on request via ClientSuccess@maropost.com.
Mailchimp offers optional US short codes through account billing on approved programs, while most accounts start with registered long-code or toll-free style numbers from the application.
Maropost uses a pool of shared short codes (US/Canada) and long codes (other countries) across clients. Each message may show a different sender number unless you purchase a dedicated short code.
Mailchimp assigns brand-specific approved sending numbers per SMS program rather than rotating unrelated shared short codes across unrelated clients on every message.
Maropost maintains an account-wide SMS Do Not Mail suppression list. Anyone on it will never receive SMS from your account, and contacts with permanent delivery failures are added automatically.
Mailchimp processes STOP opt-out replies and maintains suppression so unsubscribed SMS contacts do not receive additional marketing texts.
Maropost warns you when scheduling a campaign outside permitted hours, with Pause (default) or Send Anyway options to prevent accidental compliance violations.
Mailchimp relies on merchant scheduling and program rate limits rather than automatically blocking every broadcast that might fall inside quiet-hour windows.
Maropost lets you replace the default mpt1.co short domain with your own branded domain for SMS links. Add a CNAME DNS record and verify ownership in Settings.
Mailchimp shortens links automatically in SMS messages and supports branded SMS short-link subdomains on eligible plans for click tracking.
Maropost supports teams messaging Texas residents under Texas Senate Bill 140 (effective Sept 2025), which requires registration via Form 3401, a $200 annual fee, and a $10,000 security deposit.
Mailchimp publishes SMS compliance requirements in the application workflow, but merchants remain responsible for state registrations such as Texas SB 140.

Mailchimp captures SMS opt-ins through signup forms, landing pages, QR codes, and checkout or onsite collection flows with required compliance disclosures.
Maropost supports double opt-in when enabled on a form with a phone field: the SMS contact is only added after the subscriber confirms via email. You must disclose SMS consent clearly since double opt-in is email-based.
Mailchimp supports compliant SMS opt-in collection with explicit affirmative consent and documented signup metadata such as timestamp and source where configured.
Maropost lets you bulk import phone numbers from CSV or TXT files, mapping phone column, optional subscription status (S=Subscribed, U=Unsubscribed), and optional UID column.

Mailchimp targets SMS campaigns using audiences, segments, tags, and ecommerce data from connected Shopify, WooCommerce, and other store integrations.

Mailchimp does not offer a native Retail Express integration for syncing in-store retail customer phone fields and SMS preferences into its platform.

Mailchimp forms and landing pages support display logic, targeting, and conditional visibility for collecting SMS consent alongside email on connected sites.
Maropost landing pages can be used as destinations for SMS campaigns and as acquisition surfaces to collect mobile opt-ins.
Mailchimp signup forms and QR opt-in flows provide landing and onsite paths for SMS list growth with tracked consent and audience membership.
SMS Marketing Automation, Two-Way SMS & Journeys
Maropost lets you define mobile keywords, specific words or phrases (e.g. JOIN, SALE), that contacts can text to your number. Each keyword links to an action and an automatic response message.
Mailchimp supports SMS opt-in collection through signup forms and compliant keyword-style flows where regulations allow, configured during program setup.
Maropost sends a custom auto-reply instantly when a defined keyword is received. Replies can include coupon codes, links, or nested keywords.
Mailchimp handles STOP and related opt-out keyword replies automatically and updates SMS subscription status so suppressed contacts stop receiving texts.
Maropost handles inbound replies by matching text against active keywords within a 2-hour window. Valid keyword matches get the keyword response; everything else gets the invalid response.
Mailchimp provides limited two-way SMS handling focused on compliance opt-outs rather than a full conversational SMS inbox for marketing support teams.
Maropost supports text-to-win contests: promote a keyword (e.g. WIN2026), add contacts who text in to a list, then pick a winner from subscribers and notify them via SMS.
Mailchimp Customer Journey Builder and Campaign Manager can orchestrate promotional SMS touchpoints when journeys are configured with SMS steps for engagement programs.
Maropost powers back-in-stock alerts with keywords on out-of-stock product pages (e.g. STOCK42). When the item is restocked, deactivate the keyword and Maropost SMS everyone who subscribed with a link to buy.
Mailchimp journeys and automations can trigger cart and browse-related SMS when connected ecommerce stores feed behavioral data into audience segments and journeys.
Maropost lets you add an SMS step inside automated customer journeys alongside email actions. The journey engine sends the right text at the right point in the customer lifecycle without manual intervention.
Mailchimp Customer Journey Builder adds SMS touchpoints on multichannel journeys alongside email and other channels for SMB lifecycle workflows.
Maropost's Send SMS journey widget includes its own Compliance tab so you can verify legal content before the journey goes live.
Mailchimp applies SMS program compliance settings and opt-out language to journey SMS steps configured through the SMS builder and journey editor.
Maropost automatically pauses journey SMS messages when they would send outside permitted hours for a contact's timezone, then resumes when the window opens.
Mailchimp journey SMS sends follow journey scheduling and audience rules but do not include enterprise-grade quiet-hour auto-queue controls on every tile.
Maropost skips the Send SMS journey step silently when a contact has no linked SMS phone record, then continues them to the next journey action.
Mailchimp journey branches and audience splits can route contacts without SMS consent to alternate email or non-SMS paths when journeys are configured accordingly.
Maropost delivers transactional SMS for automated, event-triggered messages like order confirmations, password resets, and OTP codes. Create templates in the UI and trigger sends programmatically via REST API when events occur.
Mailchimp Marketing API supports creating and sending SMS campaigns programmatically, though transactional OTP flows are not a native marketer deliver UI.
SMS Marketing Platform Analytics & Attribution
Maropost provides a per-campaign dashboard after send with message preview, performance tiles (sends, delivered, replies, clicks), drill-down reports, and campaign metadata.
Mailchimp provides an SMS Overview dashboard with performance metrics, recent messages, credits, onboarding checklist, and campaign engagement summaries.
Maropost shortens all URLs in your SMS body to trackable links on mpt1.co when click tracking is enabled (default ON), so you can measure clicks per link in the campaign dashboard.
