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.
Postscript
Pros
- Built around Shopify, so store data drives segments, flows and attribution with little setup.
- Starter has no platform fee, and message rates fall on the higher tiers for high-volume senders.
- Every plan includes unlimited segments, a visual flow builder with templates and response management.
- Holds about a 4.7 rating across more than 1,100 Shopify App Store reviews.
- A $100 trial credit lets stores test real sends before choosing a plan.
Cons
- Covers texting only. Email is on a waitlist, so most stores need a separate email platform.
- Starter charges the $49 minimum even in months with no sends.
- Live chat support requires Growth or higher, and recent reviews criticize the move to AI-first support.
- Some merchants report annual contracts that renewed for another year without them noticing.
- Built for US and Canada; comparison articles report international SMS at about $0.25 per message.
