Sender: Email marketing platform
Sender is an Email marketing platform. Starting at $10/mo, it targets Small senders who want automation and SMTP on a genuinely free plan. Our verdict: Customer service 4.9, the highest sub-score measured on this site. Watch for: Eight verticals banned by name, and no independent deliverability figure at all. Rated 7.3/10 overall across ease of use, deliverability, and pricing value.
What is Sender?
Sender was founded in 2012 in Vilnius by Edgaras Vaitkevičius and has taken no disclosed outside funding, which is unusual in a market of venture-backed platforms. Its own site counts more than 180,000 customers, served by a team of about thirty.
The free plan is the reason to know the name. It holds 2,500 subscribers and 15,000 emails a month, several times the mainstream free allowance, and it is not feature-gated: automation, landing pages, signup forms and transactional mail over smtp.sender.net all work on it. Most competitors put automation behind the first paid tier.
