Lob Address Verification vs Postalytics

Lob Address Verification checks address data to help determine whether addresses can be delivered. Its APIs validate one address or a batch, and Lob says it can also check and standardize addresses while customers enter them on a website. Results can add delivery and geographic details, including ZIP+4, carrier route, address type, latitude and longitude, plus a confidence score based on its mail delivery data. The product page lists delivery data for more than 240 global territories and USPS CASS certification. Integrations include AV Elements, Shopify Address Cleanser, Airtable Address Cleanser and Zapier; the interactive demo provides examples in cURL, TypeScript, Node, Ruby, Python, PHP, Java, Elixir and C#. Lob says it encrypts data in transit with TLS 1.2+ and at rest with AES-256, and provides automatic redaction and data retention policies. Developer has no subscription fee; listed paid pricing starts at $20/mo (annual). A 30-day Enterprise trial is available for high-volume senders; print and postage are billed separately at discounted Enterprise rates.

Postalytics automates direct mail campaigns, from creating personalized mail to sending it and tracking delivery and responses. Its Direct Mail Editor lets teams design, proof, and organize templates for postcards and letters. Campaign dashboards use Intelligent Mail Barcode tracking for delivery, while personalized URLs and QR codes provide response tracking. Connected automation tools can trigger postcards or letters, and lists can be imported through integrations or file upload. Postalytics says it checks addresses against USPS databases. Its integrations include HubSpot, Salesforce, HighLevel, ActiveCampaign, Klaviyo, Canva, Figma, Zapier, Marketo, Zoho CRM, and Keap; API and webhook options are also available. Supported formats include several postcard sizes, bifold self-mailers, and letters. The service says customers can mail one piece or 100,000 without a minimum order. Plans include printing, addressing, postage, and mailing services, with USPS First Class and Standard Class options. The free plan has one user login and charges mail per piece. Paid plans start at $199 per month, with mail also charged per piece. Postalytics is available on the web and through an API.
