02Pricing compared
Postscript publishes more of its pricing, but its free Starter tier still has a $49 monthly minimum spend. Starter messages cost $0.009 per SMS and $0.045 per MMS, plus carrier fees. Growth is $100/month, with rates of $0.008 per SMS and $0.03 per MMS; Professional is $500/month, with lower message rates. Annual prices are not published, and monthly billing is available without a contract. The separate Postscript AI Plan is $699/month, with additional per-message rates that vary by product and message type.
Attentive does not publish monthly or annual prices. Its quote depends on message volume and subscriber-list size, so ask for the channel breakdown and any AI add-on charges before comparing totals. Postscript’s listed rates make budgeting easier, but they do not make it automatically cheaper.
03Features and depth
Both platforms cover SMS, email, and RCS, but their channel lineups differ. Attentive also lists push, alongside audience targeting, dynamic segmentation, sign-up units, customizable reports, and compliance and deliverability tools. Its channel packages range from SMS/MMS/RCS to a package with SMS, email, RCS, and push.
Postscript focuses on retention marketing, with SMS campaigns, subscriber capture, email, and shopper journeys. Its feature list includes branded-profile RCS, onsite opt-in, and Infinity Testing for message optimization. RCS is listed as an Enterprise option, rather than a stated inclusion in every plan. Postscript’s $699/month AI Plan includes Brand Center, Infinity Testing, and Shopper, with per-message charges that vary by product and message type.
The practical split: Attentive has the broader stated channel mix, while Postscript publishes more detail on SMS rates and offers SMS-specific plans. Compare the exact channels, AI features, and message fees in each proposal; the feature lists alone do not show which platform will cost less at your volume.
04Ease of use and learning curve
Our review scores give Attentive a slight edge for ease of use: 7/10 versus Postscript’s 6/10. Those are review scores, not a guarantee that either platform will be easier for your team. Attentive lists onboarding with its Enterprise offer and dedicated support; Postscript lists live chat and email support on Growth, with priority support on Professional.
Neither source publishes migration terms, timelines, or a detailed onboarding scope for every plan. Ask both vendors what they will move, who handles setup, and whether support or onboarding costs extra. Postscript’s published plan structure makes the SMS price comparison clearer; Attentive’s channel and volume-based quote needs more clarification before you can judge total cost or implementation effort.
