Pros & Cons
AAmazon SES
Pros
- The a la carte rate of 0.10 USD per 1,000 emails is one of the lowest in the category, and several comparison articles call SES the cheapest option by volume.
- Tiered rates continue past 100M emails per month, so very high-volume senders can grow without changing providers.
- It supports SPF, DKIM and DMARC authentication, TLS 1.2 and above, and KMS encryption for mail stored in S3.
- Optional dedicated IPs, BYOIP and Virtual Deliverability Manager give large senders control over their sending reputation.
Cons
- New accounts start in a sandbox and must request production access, and users on re:Post and Reddit complain about denials.
- There is no visual campaign builder, marketing automation or landing pages, so marketers need a separate tool on top of SES.
- Reviewers on Capterra and G2 report a learning curve and setup effort, including configuring SNS to handle bounces and complaints.
- Hands-on support requires a paid AWS support plan, and add-ons such as VDM and dedicated IPs raise the total cost.
Stamped
Pros
- Rated 4.7 stars from about 3,700 reviews on the Shopify App Store, and 91 percent of those ratings are five stars.
- Review submissions can automatically award loyalty points, which links the reviews and loyalty programs.
- Reviews can be syndicated to Google Shopping, Meta, and the Shop App.
- Integrates with Klaviyo, Attentive, Omnisend, Gorgias, and Shopify Flow.
- Many merchants praise hands-on support and the free review migration.
Cons
- Merchants report slow or missing widgets, a backend that fails to load, and settings that reset.
- Some users report billing disputes, including charges after uninstalling, because billing can run outside Shopify.
- Prices on Stamped's site, which start at 199 dollars per month per product, are much higher than the entry Shopify listing, and pricing depends on order volume.
- Stamped does not run full email or SMS campaigns, so brands need a separate tool such as Klaviyo.
- Reviews and loyalty have historically been separate apps, which some users find confusing to set up.
