Pros & Cons
OneSignal

Pros
- A free plan with unlimited push up to 1,000 MAU and 10,000 emails a month makes it cheap to start.
- Push, in-app, email and SMS run from one platform with cross-channel journeys.
- Reviewers on G2 and PeerSpot say the dashboard is easy for non-technical marketers to use.
- A broad integration catalog covers CDPs such as Segment, RudderStack and Hightouch, data warehouses, and analytics tools.
Cons
- PeerSpot reviewers call it expensive for large subscriber bases.
- Free and Growth plans cap segments at 6 and 10, and reporting history at 30 and 90 days.
- SMS pricing is not published and requires a sales conversation.
- Reviewers mention unclear documentation for advanced cases and limited in-app design options.
Semrush

Pros
- Very large keyword database, cited at 26.8 billion keywords across 142 country databases, with intent tagging and clustering.
- One subscription covers SEO, PPC research, content, link outreach and AI search visibility tracking.
- Daily report limits do not use a credit system, and reviewers find them more generous than Ahrefs at similar prices.
- A free plan and a 7-day trial on paid plans let buyers test it before committing.
- Integrates with Google Search Console, Google Analytics, Looker Studio, Zapier and Make, with MCP access from the Starter plan.
- SplitSignal runs SEO split tests that compare page groups and estimate the effect of on-page changes on organic clicks.
Cons
- Each plan includes only one user, and extra seats start at 45 dollars a month, so team costs rise quickly.
- Many users complain about two-step cancellation and billing disputes, and Trustpilot scores are around 1.6 to 2.1.
- Monthly plans are not refunded, and the one-time refund covers only annual plans within 7 days.
- The dense interface shows tools your plan does not include, and beginners face a learning curve.
- Historical data requires Pro+, and full API access requires the custom Advanced plan.
- Traffic and volume figures are estimates and can differ from Google Search Console for low-volume keywords.
