An email service provider (ESP) is a platform that sends bulk or automated email for you and manages authentication, deliverability, lists, templates, analytics and compliance. Learn the three types and how to choose.
Connect Salesforce to Bluey Email so CRM events sync contacts and trigger email via Flow, webhooks, Zapier, or the API. Includes the highest-value Salesforce automations and when Marketing Cloud fits better instead.
Connect WordPress to Bluey Email so form submissions, WooCommerce orders, and leads flow into your list via an embedded form, Zapier or Make, or the API. Includes the best WordPress-to-Bluey automations to build first.
An email bounce is a mail server rejecting your message. Hard bounces (5.X.X) are permanent, soft bounces (4.X.X) temporary. Postmark says bounce rate should never exceed 10 percent; aim under 2 percent and remove hard bounces.
Warming up a new sending domain means starting with low volume to engaged recipients and ramping slowly over weeks. Authenticate with SPF, DKIM, DMARC first, never spike volume, and keep spam complaints under 0.1 percent.
The email metrics worth tracking are open rate, click-through rate, click-to-open rate, conversion rate, bounce rate, unsubscribe rate, and spam-complaint rate. Mailchimp puts the all-industry open rate at 35.63 percent and click rate at 2.62 percent.
Loops bills by subscribed contacts with unlimited sends; Bluey Email bills by sends with unlimited contacts on Grow. Which is cheaper depends on your list size versus send frequency.
Double opt-in means a subscriber confirms their email address by clicking a link before joining your list. It is not required by GDPR but is widely considered best practice for list quality and deliverability.
There is no single right email frequency. Anchor to what you promised at signup, send only genuinely valuable emails, and let engagement and spam-complaint trends set your cadence rather than a calendar.
Email list cleaning removes invalid, mistyped, and long-inactive addresses so you only mail people who can and want to receive it. It protects your sender reputation, and validation catches bad addresses before they bounce.
