Owletter sees their email.Sendsitive sees the texts too.
Your competitors run email and SMS off the same calendar, and half of it is invisible to an email-only tool. Sendsitive captures both in one archive from $14.50 per month, and you can read the brand pages before you pay anything.

Sendsitive is a self-serve alternative to Owletter for competitor marketing intelligence. Like Owletter, it subscribes to a competitor's list for you, captures every campaign automatically and keeps it searchable. Unlike Owletter, it also tracks the SMS and MMS those brands send, every tracked brand has a public page at sendsitive.com/brands that needs no account, and plans start at $14.50 per month instead of $29.
Side by side, honestly
Owletter is a solid email monitor and it has been doing this longer than we have. The question is whether email is the whole picture. A brand that texts you a 20 percent code on Friday and emails the same offer on Saturday shows up once in an email-only archive, and the channel that got the click is the one you cannot see.

Common questions
- What is the difference between Owletter and Sendsitive?
- Coverage and access. Owletter captures the emails a competitor sends to its list; Sendsitive captures those and the SMS and MMS campaigns they send to their texting list, in one archive. And Owletter needs a card before you see a competitor's mail, while Sendsitive publishes a page per tracked brand with subject lines, send times and previews that anyone can read with no account. On price, Sendsitive starts at $14.50 per month for 5 competitors against Owletter's $29 for 10.
- How much does Owletter cost?
- As of September 2026, Owletter lists Starter at $29 per month or $290 per year for 10 websites, Pro at $49 per month or $490 per year for 25 websites, and Unlimited at $99 per month or $990 per year for unlimited websites. Every plan has a 14-day free trial and annual billing gives two months free. Sendsitive lists Basic at $14.50 for 5 competitors, Starter $24.50 for 10, Pro $49.50 for 25 and Business $99.50 for 50 with 3 seats.
- Does Owletter track competitor SMS?
- No. Owletter captures emails sent from a website to its mailing list and screenshots them. It has no text message coverage. Sendsitive tracks SMS and MMS alongside email: a dedicated US number for your organization subscribes to a brand's texting program once, and every message is archived with the media, the timing and the offer. As of 2026 Sendsitive is the only self-serve platform covering both channels.
- Is there a free plan?
- Sendsitive has one. Every brand it tracks has a public page at sendsitive.com/brands with subject lines, send times, cadence and previews, readable with no account (2,400+ campaigns from 50+ brands across 22 categories). A free account opens the full emails and the Explore archive of the last 15 days with search and filters. Tracking your own competitors starts at $14.50 per month. Owletter has an instant demo and a 14-day trial on its paid plans, but no free tier and no public archive.
- What does Owletter do better?
- Their Unlimited plan tracks unlimited websites for $99 per month, so a competitive set larger than 50 costs less there than on Sendsitive Business. Every Owletter plan gives the whole team access to the archive, while Sendsitive Basic is one seat and Starter and Pro are two. Owletter also screenshots every captured email and can send scheduled daily, weekly or monthly roundups to colleagues, neither of which Sendsitive does today.
- Can I switch from Owletter to Sendsitive?
- Yes, and there is nothing to export. Add the same websites as competitors in Sendsitive, drop each new capture address into the brand's signup form, and the archive starts building that day. Most people finish in under half an hour. Your Owletter history stays in Owletter, and Sendsitive's public archive already holds recent sends from many brands, so the feed is rarely empty on day one.
