Thank Me Later is a popular open source WordPress plugin that sends ‘thank you’ emails to a blog’s commenters.
Time delay. The idea is to grab a commenter’s attention and bring them back to your blog. Sending an email straight away doesn’t make much sense. You can delay your message for a week (for example), and prompt commenters to return to your blog and further engage with conversation.
Personalisation. Include a commenter’s name, comment or post title in your email message for a more personal touch. ‘Sarah, thank you for your comment on My Cool Web Links’ is more attractive than ‘Thank you for your comment’.
Targeting. Create targeted emails for categories or specific posts on your blog. Targeted emails are a great way to make email messages more relevant to the user, and makes them more likely to return to your blog.
HTML emails. Send beautiful HTML emails to your commenters.
Reviews & Feedback
This plug in [...] goes one step further. [...] The email message is very customizable with tags that represent several variables in the comments. Richard Hay, Weblog Tools Collection. May, 2009.
This plugin is great. It sends an email to all first-time visitors. You can write up the email to remind them about your RSS feed or just to invite them to connect with you personally. I do both. Nicholas Cardot, Site Sketch 101. January, 2010.
There are a lot of ways to customize your message, from the content to when the thank you note is sent out, making it really versatile. [...] Sending a little note can put a more personal face on your website, encourage them to subscribe to your RSS feed or email newsletter, start fostering relationships with your commenters, etc. — all things you want to do to help build your brand and reputation. Addicott Web. March, 2009.
This is great for encouraging further interaction with your blog, whilst providing a direct promotional opportunity to visitors, more importantly the email will be timely, sent whilst the visitor has your brand in mind! Republiquedesign. February, 2010
