According to Live Direct Marketing's daily Tranco top-1M scan (July 13, 2026), AWeber is the email service provider (ESP) for 311 domains — 0.05% of 617,702 SPF-publishing domains. Detection method: include: mechanisms in the SPF record.
AWeber is an email service provider and marketing automation platform that enables businesses to build and send campaigns and automate customer communications. It is operated by AWeber Communications Inc., a US-based company.
AWeber's footprint across the internet is distributed across the long tail of smaller websites rather than concentrated among the largest global brands; it is predominantly found in .com domains. The frequent co-occurrence of AWeber alongside Google Workspace suggests positioning in the small-to-medium business segment. For email administrators and deliverability professionals, understanding this footprint pattern matters: senders using AWeber are likely SMBs with varied authentication practices and less-established sender reputation than enterprises, meaning that AWeber's infrastructure reputation becomes a shared factor in inbox placement decisions.

When a smaller business uses AWeber to send email, it publishes an SPF include mechanism that authorises AWeber's infrastructure on that domain's behalf. This creates an authentication and reputation chain: the receiving mail server verifies SPF compliance, but inbox placement also factors in the infrastructure's history. Because AWeber's customer base is concentrated in smaller businesses with varied authentication practices and less-established sender reputation, the reputation of AWeber's infrastructure itself becomes a shared factor in deliverability outcomes.
