Subject line help!?

[Brent P.]

I was hoping to get some opinions. I am conducting several email campaigns for a new free webinar series my company is hosting. I have scoured the internet for some good ideas for subject lines and intend to do multiple rounds of A/B testing, but thought i would get some candid opinions on the ones i developed so far. Please vote, if you don't mind, for your two favorites or if you have any strong opinions or ideas for better subject line templates let me know:

1. Speaker Name - Speaker event title (John Simpson - The 7 best social media strategies)

2. From Speaker Name - important [related topic] information (From John Simpson - Important social media information)

3. Question about the event topic (Do you know the best social media strategies?)

4. Inside business: [event topic] (Inside business: Social media strategies)

5. Invitation for [persons name] (Invitation for Jane Smith)

6. Part 1: Business Webinar Series (part 2, part 3, etc)

7. Business Webinar Series - [event title] (Business Webinar Series - Top 7 Social Media Strategies

Thank you for help if this gets any replies!~
