Track your competitors' SMS marketing. Word for word.
A dedicated US number for your organization. Subscribe it to a brand once, and every text and MMS they send is captured from that moment on: offers, cadence, creative, and timing, side by side with their email.
- SMS included from the Starter plan
- Your personal number stays private
- US messaging programs
Competitor SMS tracking means subscribing to rival brands' text message programs with a number you control, then archiving and analyzing everything they send. As of 2026, Sendsitive is the only self-serve platform that does this alongside email: SendView tracks email only, MailCharts moved to enterprise-only contracts in late 2025, and inspiration archives like Milled carry no SMS at all. If a brand in your category runs text marketing, this is where you see it.

What SMS intelligence includes
Dedicated US number
Provisioned in one click for your organization. One number, every brand you track, zero exposure of anyone's personal phone.

Brands gate their lists behind double opt-in. When the confirmation prompt arrives, Sendsitive replies with the standard keyword for you.
MMS media archived
Images and creative arrive with the message and stay with it. See the visual a brand paired with the offer.
Channel mix analytics
How much of a competitor's volume is SMS versus email, and when each channel fires. Questions no email-only tool can answer.
Unified timeline
Texts appear in the same feed, list, and detail views as email campaigns, attributed to the right brand automatically.
Compliance built in
STOP is honored automatically, outbound is limited to standard subscription keywords, and consent is recorded when your number is provisioned.
Every number above is live. See it yourself in the public brand archive, no account needed.

Common questions
- Can I track my competitors' SMS marketing campaigns?
- Yes. Sendsitive assigns your organization a dedicated US phone number. You enter that number into a brand's own SMS signup form once, Sendsitive confirms the double opt-in automatically, and from that moment every text and MMS the brand sends is captured, archived, and analyzed alongside their email campaigns.
- How does competitor SMS tracking work?
- Three steps. First, Sendsitive provisions a dedicated US number for your organization, so your personal phone is never exposed. Second, you subscribe that number to each brand you want to watch, through the brand's own public signup form, one time per brand. Third, everything after that is automatic: the double opt-in confirmation, message capture, MMS media archiving, attribution to the right brand, and timing analytics.
- Does Sendsitive capture MMS images too?
- Yes. MMS media is archived with the message, so you see the creative a brand sent, not just the text. Media appears on the message detail page along with sender, timing, and link information.
- Is tracking competitor text messages legal?
- You are subscribing to public marketing programs with a phone number your organization controls, the same way any consumer joins a brand's SMS list. Compliance obligations for marketing texts (TCPA, CTIA) bind the sender. Sendsitive honors STOP automatically, sends only standard subscription keywords, and never sends marketing from your number.
- Does SendView track SMS?
- No. SendView tracks email only, as of 2026. Sendsitive tracks both channels, which is what makes channel-mix questions answerable: how much of a competitor's volume is SMS, who leans hardest on text, and how their SMS cadence compares with email.
- Is there a MailCharts alternative with SMS tracking?
- MailCharts discontinued its self-serve plans in late 2025 and now sells enterprise contracts only, with quote-based pricing and no trial. Sendsitive is the self-serve alternative that covers both email and SMS, starting at $49 per month with a 7-day trial path through the Basic plan.
- Do the tracking numbers work outside the US?
- SMS tracking currently covers US messaging programs: the dedicated numbers are US numbers and brands' US SMS lists deliver to them. Email tracking works globally. International SMS coverage is on the roadmap.
