Poplar review

Poplar targets online brands that want mail to behave like a performance channel. The free plan already covers CSV uploads, audience management, real-time attribution, delivery tracking, lookalike modeling and email-to-address retargeting, so a store can test mail without a subscription. Lite at $249 per month adds a dedicated account manager, site visitor retargeting, dynamic creative and lower piece prices, and Pro at $499 per month adds strategic support and custom data sourcing. Per-piece prices are published for each tier: a 4x6 postcard is $0.73 on Free, $0.66 on Lite and $0.55 on Pro, with letters, bifolds and trifolds listed too. Integrations focus on the ecommerce and lifecycle stack, including Klaviyo, Shopify, Braze, Iterable and Segment, and the company cites SOC 2 Type II compliance. B2B teams that live in a sales CRM will find fewer native hooks than Postalytics offers.
